Sorry to turn up this old thread, but I found it googling for driveshaft lengths, and this info is HARD to find.
This info is added now for any future google travelers, just to make there lives just a little bit easier.
Explorer aluminum driveshaft (4 door 2wd were only ones with aluminum) = 50.75" long. Since it was also asked in this thread... 1979-04 Mustang shafts = 45.5" long And just to top off the Fox body info... a 1978-83 Fox Fairmont driveshaft = 50.5" long.
Hope this helps some future googler, and maybe even someone on the site today! Dave
Edit: What the heck... here's more. Crown Vic aluminum shaft = 55.5" Mark 8 aluminum shaft = 58.2" (However, 93 was the only year for the desireable 1 pc shaft)
For speed density, these are the computers that you can use (all listed for automatic transmissions): ■DA1 (1987-88 Mustang) ■DB1 (1987-88 Mustang) ■DX3 (1987 Mark VII) ■VL2 (1987 Mark VII) ■DY3 (1988 Mark VII) ■D9S (1988 Mark VII) THESE WILL ALL FIT YOUR CARS..
DA1 is a manual trans computer. My 87 GT uses that one. Shouldn't be used with autos from what I am told.
The u-pulls here have a good stock of Fox cars, the thing is that you have to get to them quick. Once they have been in the yards for a few days, they have been picked and abused beyond use by others. They will go after a certain part, and if they rip everything else to shreds to get to that part, they don't care. It's sad...
Says it will outflow the tube and the cobra intake?
FWIW: The GT40 family of upper intakes varies pretty wildly in flow. The top performers are the stock 93 Cobra and 94/95 Cobra versions. The Lightning/tubular version does not have a high peak flow, but it's rpm range is very broad and flat compared to the others, which makes it great in it's own right. The Exploder versions are the lowest flowing uppers by far, but still better than the stock 5.0 style Fox intakes any day.
The u-pulls here are always well stocked with V8 Exploders, and my buddy who works at one says they go for $30-$50 bux each, depending on the mood of the counter guy.
Looks to me like someone redrilled the axles/rotors with the standard car bolt pattern. Most large FoMoCo cars in the 60s-70s, like Lincolns and T-Birds had a large, non-standard bolt pattern. They did a good job. I can't tell, but they might have even put 'new' axles in it with the correct bolt pattern.
One thing though, those brakes are old tech, somewhat complex, and prices on parts are going up the older they get. You could possibly swap on some late model Crown Vic/Exploder rear discs, depending on which ends are on the axle tubes. Small bearing 9"/big bearing 8" ends can use the Vic rear discs, while 'New' big bearing 9" (or sometimes called Torino bearings), use the Exploder rear discs. The nice thing about the newer discs, besides cheap and plentiful, is that the E-brake setup is a drum setup, and drum brake E-brake cables are an easy swap.
Edit After another look, they redrilled the axles. You can see the old stud holes under the rotor. Another thing to note, it's possible that the rear is a 9 3/8" Ford rear. Those oversize cars with large bolt pattern wheels usually had the 9 3/8". It is almost identical to a 9", and you can even directly convert the housing over to all 9" parts. I am not sure what does and does not interchange (regarding the diff and gear set) if you try to hybrid them, but a complete parts swap is supposed to be direct.
Love those cars. We bought one about 2 years ago that looks exactly like yours (except blue interior). It was so full of rust holes around the rear window we had to junk it. The engine and tranny went into my son's 81 Fairmont Futura. I wish we could have kept the car. It only had 70k miles! Got it from an elderly couple for 500 bux.
