      69 Mustang SuperCoupe

      I've been on these forums for a long time and have never made a build thread for my car, mostly because of the slow progress. Well I decided to create one to somewhat document the progress such that it is.

      Some background. This car is the 3rd (of 16)(2nd 69) mustang I've owned. I bought it in December 1983 when stationed at Blytheville AFB Arkansas. It changed hands a couple of times before I got it but had come from Texas with a young airman. It actually got the 351C engine from my 72 Gran Torino sport at one time. It had a 351W 3 spd in it by the time I got it. I drove it for a while even moving it when I transfered to Grissom AFB Indiana. Sometime around late 84/early 85 I traded my frozen 429 SCJ motor I had for the 72 Gran Torino Sport for a 70 351C with completed machine work and ready to build. I built the cleveland and swapped out the windsor replacing the 3 spd and 8 inch rear with a close ratio 4 spd and 9 inch with 3.00-1 gears from a 70 cougar at the same time about March 85. I drove it pretty regularly till mid October 86 when I decided to rebuild the car. It's been in various states of dis-assembly ever since.

      This past fall I contacted Ben on these forums and contracted him to do a rendering for my car as inspiration and to help motivate me to do more. I'm not getting any younger! This represents my vision for at least the exterior of my car.



      Condition when bought.

      Marti report



      I modeled the framing and interior layout in SolidWorks several years ago as I was redeveloping my plans for the car. Not 100% accurate but useful nonetheless.



      The rear frame rails from S&W Racecars tacked up





      Framing in process









      Rear bumper mounts





      New taillight panel & filler mod









      Right quarter panel cut out, new outer wheelhouse welded in. Old one trimmed 2 inches otbd of flange & new one mated to it with flange trimmed off.





      Fabbing right quarter scoop & ducting.

      Lower dash mod









      I may tinker with it some more as I'm not 100% satisfied with it.

      My stainless steel gas tank. It has a sump area below the larger opening. The sump has openings on each side and covered with SS mesh. I've filled the tank with fuel cell foam blocks to minimize fuel sloshing. The bottom panels angle towards the sump at about a 20 degree angle.

      I supplied the SS pieces and a friend Tig welded it for me.

      The 9 inch rear is getting 3.50 gears replacing the 3.00 ones. I'm also going to try the Power Trax No-Slip set up for the differential. I have all new ARP hardware for it also.

      The engine is a 70 351C 4V with closed chambers.

      Before I started disassembly.



      I've been buying parts here & there. I have all new ARP hardware, thermostat & housing, Quick Fuel SS-750-AN carb, Hamburger 1" carb spacer, MSD ignition system, Romac double row timing set, Aluminum external oil filter adapter, Hamburger remote filter mount, Mallory electric fuel pump & regulator, Aeromotive primary & secondary fuel filters, Aluminum fuel pump block-off plate, Milodon water pump, Moroso oil breather tank & coolant overflow tank, G+ oil cooler, gauge sending units and Felpro gasket set. I'll be reusing my Offenhauser Port-O-Sonic intake. I'm contemplating dry sumping the oil system or at least using an external pump.

      Intake cleaned up and painted with Eastwood's ceramic engine paint. I really like how it turned out.





      I'm wanting to pull the heads soon and have them rebuilt so I'm currently thinking through the cam and associated valve train I want to use. The top of the short list is Howards P/N 230245-12,

      Making a mount for my coil to attach to the front of the left head.














      Modified my throttle cable bracket for new aftermarket cable.

      Street, I don't think it would pass any sanctioning body rules with some of my modifications. No big deal though.

      I would not use the Powertrax but get a limited slip.... I had one... gave me traction on both wheels but was a pain in the corners.... just a bit of throttle and it locks causing wheelspin in a corner....specially in the wet it is just dangerous. It is just nice for drag racing.

      Thanks Martin. Since I already have it, guess I'll see how it goes. I can always swap it out later.

      Got my Scott Drake billet grille from CJPP. First one they sent was bent & distorted, got a replacement a week later.


      Received my LED taillights this week.


      Sandblasted the bottom flanges and found a bunch of pinholes in one.



      Started to weld them closed and shortly after decided it was a lost cause. Also decided to modify the housings by hacking off the back and moving the socket to the left side. Don't need that space anyhow with the LEDs in the lens. Plus gain back some trunk space.







      I need to do a little more cleanup, POR15, then paint. I'll do the other one after I finish cleaning this one. I have new gaskets and hardware also.

      I started working on the door caps for standard door panels. Removed the interior window weatherstrip, straightened the flange afterwards. Ordered new weatherstrip and lock knob grommets. Have to finish cleaning then paint them. I hadn't taken any pics of them.

      Nice build. I'm interested to see what your plan is for the lower dash center section. I have a 69 Cougar which has the same factory lower dash as the Mustang. I moved the AC vents down to the factory radio slot to allow for a Pioneer Carplay head unit to be installed in where the vents used to be. I installed the Vintage Air controller in the factory HVAC control area but it is very hard to see the controls there. So i'm curious what your idea is.

      Good Luck

      Great work, I LOVE garage-built cars.
      Cars are meant to be driven.

      Thanks
      Moving the vents sounds like a good solution.
      Plan is switches, USB ports and different heater controls. Haven't nailed down the heater controls yet. I have a vision for a remote audio system which has yet to be defined.

      It's more like rear bulkhead framing. With no rear seat, the area behind is partially open to the rear suspension. How far it intrudes vertically on the space behind the seats depends on the yet-to-be-determined upper link mounting of my 3-link and space needed for mufflers forward of the axle.

      Finished up the taillight housings a few weeks ago.



      Blacked out the trim then assembled


      Stripped, cleaned & primed the interior upper door trim


      Threw some primer on my air dam to check the contour and smoothness. Still have some sanding and skim coating to bring it where I want it.

      I've always liked the styling of the 69/70 coupes, especially since the FB's are so overpriced. Aren't you concerned about the extra weight of all the square tube?
