Cleaning up odds and ends: clutch pedal, hoses, e-brake, AL panel install


Vintage air system install.  I keep complaining about it just in case you haven't figured out you should never buy this system. 

Question: how helpful are the instructions from FFR and Vintage for actually installing a working system in your Type 65:

Answer:... Nothing heard, Out.

 

I have finally made all of the connections for this air system.  As I have frequently griped for months it is severely lacking in actual application to the overall car.  Nothing fits.  I took a couple of quarters of Russian in college.  My TA was Korean who learned to speak Russian, then English.  The instructions for the Vintage air kit read like someone who took a couple of wildly different languages from English and then tried to write instructions for a system they have never seen to be installed in a car they have never heard about.  With the vacuum connection to the intake manifold I installed the final piece.  Of course whether or not it all works won't be seen for a few more months.  The pictures are of the dehydrator and trinary switch and you can see how I routed the heater hoses through the original Mustang wiring harness computer connection in the top of the passenger footbox, as well as the AC hoses themselves.  I also finally found a local A/C shop that will do custom hoses.  It is a rare skillset few places want to do anymore because it is not cheap when the crimping dies break.  I paid $12 per fitting, and considered it a bargain after the time it took to find anyone to do it.  I also forgot that I had moved the evaporator about two inches to the passenger side after fitting the revised dash ducts and hoses.  I did this to allow the heater and coolant supply lines to fit in the top of the footbox.  Thankfully I was able to just push it all back where it was originally but I need to redo the supply lines inside the footbox to the heater itself.  A minor thing after all the other struggles.  I also had to get a new drain hose as the one with the kit is about 18 inches too short to actually drain outside the passenger footbox.  One of those kind-of-important things.
 

 

 

Emergency brake: another thing that comes with dubious instructions on how to install.  The most important point is you must re-drill the mounting holes on the horizintal bracket piece with the ratcheting teeth at 5 and 11/16 inches on center to actually fit in the Type 65.  I also had to cut a separate length of 1/4 - 28 twist bolt to make the eyebolts work for it as the length is just a little too short to make it work.  Finally I had to widen the hole in the passenger floor pan so the whole thing would move without interference.  I also glued some Teflon sliders to the main frame tube underneath the car to make sure the cables moved freely without cutting grooves in the powder coat.  The picture is of the modified bolt and the final install of the brake handle from underneath the car.







 

Electrical: after much work and rework all of the electrical cables and connections are where they are supposed to be, with the exception of the fan thermo switch.  I may end up swapping that out with the heater hose supply line from the manifold.  I routed the heater hose to the back of the gooseneck for the thermostat which is typically where it runs for normal Ford 351W installs on production vehicles.  The "instructions" from Vintage Air were surprisingly less than helpful.

 

Clutch pedal: I found out the hard way that not only was the steering wheel mount installed a little off on my frame, FFR also didn't account for the new Wilwood pedal width and the old frame trusses from the front end to the dash.  My clutch pedal had about 1.5 inches of travel before it hit the 1" truss from the dash to the frame.  After considering lots of options (cutting and welding in a bend in the 1" tube, or shaving the pedal bracket down and hoping it didn't fail) my brother in law looked at it and said why don't you simply have a new pedal arm made with essentially an S curve in it.  I fab'd up a plywood piece to test the theory.  I found a local metal fabrication guy and he forged one for me (vice just cutting it out) from 1/2" high strength steel.  He made it perfectly and for 100 bucks I now have a very nice, custom pedal arm that still works with the adjustable pedals the Wilwood kit came with.  I had to use Teflon washers to get it centered in the original Wilwood pedal assy bracket but it swings freely and I have plenty of clutch now.  I shot it with a coat of appliance epoxy and installed it.  The picture shows it from the outside of the driver's pedal box where it fits perfectly and looks pretty good.  It will be hidden anyway so it really doesn't matter.  More importantly I found a fantastic metal fab guy here in Jacksonville, who can also make house calls.  Wish I had met him when I needed to fix the steering wheel alignment.  Sounds like my pedal and steering wheel problems only affected a few frames, but they are significant if ignored.
 
 




 

Aluminum panel install: After several months of procrastinating I finally started to install the interior AL panels.  It looks much more like a car now.  The main floor/transmission tunnel pieces needed some trimming for the top trans tunnel piece to fit properly.  I also modified the trans tunnel to accept a cable for the electronic clock I am installing in the center dash console, which requires a constant battery power source.  It bypasses the battery cutoff switch.  I originally painted all of the exterior of the AL panels with spray can undercoat.  For the trans tunnel top piece I did the same thing, then covered it with white exterior high gloss spray paint to provide some reflective light in case I need to solve some other problems from underneath the car.  Staring at a dark trans tunnel laying on the floor is hard enough so the white paint helps light things up.  For the trans itself because I am using the RF wiring kit, I did not need the mechanical speedo plug.  The Tremec instructions say to order the mech speedo block off plug from any authorized Tremec dealer, of which I found none when looking online.  I thought about using the Mike Forte one, which looks pretty and works very well.  It was also ten times the cost of a rubber/bolt compression block off plug from Napa.  I will be back to Mike's site though as he has lots of very nicely done add ons for these kits.

 

Next step is final dash install work.  From there I will have all gauges done (wired those harnesses almost a year ago now) and can start it and drive the gokart.  Although I haven't posted in a while I have spent some time solving the problems.  I have to be done by next May as the Navy will probably send me somewhere else.  Times a tickin'.

AC Heat ducting solved,installed foot box panels




This picture shows the top dash panel (I split my dash panel into two pieces) lifted up to show the under dash window vent on the passenger side and the main supply plenum I made to route the five dash and foot box vents into to primary lines feeding the dash.  The Vintage Air system came with seven supply ducts explained below.

After a couple months of recovering from the flu shot (down for two weeks with the nose spray version, never trust Navy medicine), travelling to the Indian Ocean, and then Norfolk I was finally able to design a supply duct to fit under the dash and still allow me to run a line to the passenger side window defrost vent.  The A/C came with outlets for seven supply lines: two for defrost, two for feet, and three for dash.  As my control panel doesn't have a separate foot and dash diverter it made no sense to keep those lines separate, and I never use foot vents on any other car I own anyway so I decided to combine them all.  Instead of five tubes for heat and feet crammed under the dash with a resultant Igor-like hump in it I combined five into two and will then split the line for the dash center and driver side vent in the middle of the dash area.  The two defrost vents still work independently but I had to design a new inlet hole and plenum to route it to the pre-cut dash vent on the passenger side.  Driver works fine with the plastic piece the kit came with.  Once again I borrowed from cbergquist1 for the basic idea and modified it for my needs.  The FFR instructions are (as previously wanked about) useless as they only really discuss mounting the compressor to the engine block and given I went with The Engine Factory's recommendation for the March Pulley mount the FFR instructions were unvaluable (as opposed to invaluable).  The Vintage Air instructions are generic to something sort of like a 40 Ford Hot Rod and explain nothing.  I have very few complaints about the whole process of building this car and ALL of them stem from this heater/ac system.  The picture shows how the two work together under the dash with the resultant four lines feeding the vent locations.  Although not visible in the photo I did cut corresponding holes in the bottom of the main supply manifold I built (the long metal box taking up most of the picture to match the five supply vents from the dash unit.  I wanted to ensure as tight a fit as possible and make it fit in the space provided under the dash panel. 

Separately, I also made the correct connections from the Ron Francis wiring harness to the corresponding sending units, coil, choke, etc.  I had to relocate the water temp sending unit as I finally got around to watching the excellent video The Engine Factory sent with my 351W and found they had explained much of what I stared stupidly at, like which port to screw the temp sensor into on the manifold.  The un-seen but named "Robert" who built the motor did a great job pointing it all out.  It finally dawned on me to watch the CD they sent with it to see how they hooked it up when they ran it.  Stupid will get you a long way, but always short of the goal. 


I am finally ready to final-install most of the cockpit panels so I ordered a box of RAMMAT acoustic mats and some of their padding.  It is far cheaper than dynamat and they make a good point that 500 degree mat doesn't matter when everything else is on fire already - including the occupant.  "Sorry ma'am, the car and your husband were destroyed in the fire but the dynamat is still intact."  I am initially just going to do the inside foot box panels as they will be challenging at best when finally installed.  This way I can cut and fit the mat before I rivet the panels in place (afternote - didn't do this as I got busy and realized I needed to wait until I had them each installed).  I will also use heat insulation on  the engine side of the fire wall, wrap the headers in exhaust wrap, and paint it all with heat resistant BBQ paint so the inside temp should be manageable, for a Cobra-style car.  Thus the decision to struggle through figuring out how to make the a/c work.  My dear wife told me to just throw it away and buy the 'other one' the smart guys use.  What I make up for in stupid I balance with stubborn.  A magic combination.  I did find though that fitting and refitting these panels, plus fitting everything else on the car before finally installing them was the right way to go.  If you follow the build manual you will not do this and will likely regret it.  I used white Silicone II (doesn't interact with Aluminum like regular silicone sealants will) and riveted everything quite solidly.  I will also do a thin bead of Silicone II along all panel seams when I am done to make sure they are water tight.

Finally I prepared the rear compartment panels with the undercoating paint.  All of them are ready and will be installed over the next couple of weeks.

For a really big deal, my friend Carl who is also a fantastic graphic artist with his computer, created a digital file to use as a basis for trying out different color options on the car.  You can literally create any color combination in the world, save the file and use it as a basis for making paint choices.  We did a few sample color panels which I will print out and compare for a few months.  It was great to see him and I really appreciate the effort he put into giving me a fantastic tool for choosing colors.  Carl my friend I can't thank you enough.

I hope you had a very Merry Christmas and are off to the beginning of a Happy New Year.
