Directfreak: yes, and it was a pita. Look into Grannies bolt in kits. I wish they were available when i did mine.

love the braaaap
Only Mustang GT's came with the 8.8. The rest had the 7.5. The best source for an 8.8 is NOT a mustang actually. A 95 or later Explorer came stock with the 8.8 and disk rear brakes, along with the 5x4.5 bolt pattern and I think its only about 2" wider than the stock rear end.

I think '79-93 mustang rearends are all 8.8" but I'm NO ford expert. A quick seach online would probably reveal this quickly.

I thought one of the V8 conversion places had a bolt on 8.8 kit. Search or ask around in the traitor's section of the rotary performance forum.
If you are going to do it yourself get an 8.8 lincoln rear end. They have big vented disk brakes.

This isn't correct, any 87-98 V8 mustang came with an 8.8 which includes LX models, Rangers, Mazda B series pickups, Towncars, MarkVIII's, LTD's, Crown Victoria's, all came with 8.8 diffs

some of the old school puerto rican racer's i know use datsun truck rear end's....i've heard they just swap over the spring perches along with the other vital sus pieces needed for the 1st gen chassis, but that sounds like some work

The best part is, the explorer came STOCK with disk brakes after 95 or 97, depending what you read, up to 4.10 gears and a Trac-Loc in some models. They also have much stronger 31 spline axles compared to the mustang 27 spline units.
Ok, further serching provided these numbers:
AXLE, 97 & UP MOUNTAINEER, 95 & UP EXPLORER, 2&4 WD 5L RH 27-5/8", 31 SPL
AXLE, 97 & UP MOUNTAINEER, 95 & UP EXPLORER, 2&4 WD 5L LH 30-1/2", 31 SPL
This means the axle shafts have a difference of about 2 7/8", meaning that the axle can be narrowed by that much. You would end up with an axle that is slightly narrower than stock. But I'm seeing some conflicting numbers. It says on the page I found that the pinion is offset 3 7/8" to the passenger side instead of the 2 3/16" I found earlier. I'll trust the new info as it seems the info was very well researched.

Its actually a thread from a jeep website as the explorer rear end is a very common swap in those.

Seems like it's going to be alot of work without one of those conversion kits but i'll give it a try. Second question is going to be a suspension setup, what kind of shocks to use etc etc??

If you can get a picture of the rear cover you will know for sure, I do believe in that year both 7.5 and 8.8" diff's were used for V6 and V8 models respectivly.
I am looking for a picture I saw recently the difference in the covers for the 7.5 and the 8.8.
I don't think just the increased power handling ability of the granny's kit is worth the price. Most people needing a stronger diff also need the extra tire space back there, I have decided to use a coilover setup mounted closer inboard, with some cutting it will provide a lot more tire space for a stronger platform

Get the foxbody mustang rear, or the grannies kit. Grannies even offers BOLT IN choices for rear brakes.
I am STILL running with no rear brakes because of incompatabilities. (long story, not going to get into it - but can be easily avoided buying the correct stuff)

I have decided to go with a grannies 8.8 bot-in. When you think about making it yourself you will end up spending more in the longrun or more headaches. I have talked t granny speed shop on the phone and will have them do mine. You can choose many different options on rear brakes also. Can't beat the price.. Ordering mine with my tax return.. Late Jan or early Feb next year..

Well, the crackhead ignored me, and when I arrive one day to his shop, he had decided to go with a 4-link setup (which is almost dedicated drag-racing setup) without my permission. He ha already cut the stock mounting points and narrowed the rear in a way that I wasn't able to use anything but the housing of the rear.
I ended up spending 3x the money to make it work right, and its still not perfect. The crackhead lost all his money, was evicted from his home, lost his shop and everything in it, and was arrested within 45 days of taking my car in.
I had to use coil-overs, aftermarket brakes (which still don't work right) and adjutable links and hyme joints to make the rear work right.
However, since all my mounting points are solid, and there's no bushings back there - the ride is stiff, and bangs around alot.
Again, back then Grannies didn't offer these bolt in kits that they offer now. Plus they use stock mounting hardware so you keep your suspension and geometry all correct. Your RX-7 will still feel like the quick and nimble Rx-7 it's always been - just with a relatively bulletproof rear.
Not to mention, they offer adapters to bolt in TII rear brakes or Ford rear brakes - so you can keep your parking/e-brake (something I do not have).

By the way Trochoid, since you have a widebody - a stock Ford (Fox Body) Mustang 8.8 would br great for you - without narrowing it. You're probably one of the few who could buy a cheap one at a junkyard and weld the mounting plates on it and be done. Your wheels would more than make any difference in width. Just my 02cents.

That's good news DF, I have about 1" of extra room on each side to clear the fenders. That may change when the 15X10 wheels show up from Japan though.
Thanks for the info and sad story. I have seen a few people who have gone down the toilet quick with crack.
I have debated about going with either a panhard or 4 link when I get to the point of changing the rearend, haven't decided yet.
