I don't think it will fit. Both cars use a 4 link coil spring suspension, but the Fox body has the springs on the lower control arms and not on the axle tubes like a G body. It also uses a different bolt pattern than a G body. 1985-1993 Mustang/Capri models are 4 bolt, and the SN95 cars are wider and use a 5 lug pattern that is not the same as GM uses. Ford 5 lug is 5 on 4.5, GM is 5 on 4.75. Additionally, The Ford uses a drive flange to mount the U joints to the pinion whereas GM has direct mounting. Now, it may well be that there is a model that is the correct width out of a Fox chassis Ford, I don't know. If you want to try and see if something fits with a tape measure, here's the basic models that have 8.8's in Fox cars: 1985-1993 Mustang with 5.0, 1987-88 T bird turbo coupe, Lincoln MK VII, 1994-2004 Mustang. It may also have been used in the extremely rare LTDII LX which used a Mustang GT drivetrain and was only available in 1985. I am not sure on that one. It may even have seen duty on T-bird's and Cougars with the 5.0, but I tend to believe they had the 7.5 instead. This is all off the top of my head, so I may be wrong on some of it.

A place called TRZ motorsports was working on building a kit for this. I think they were building it for an 8.8 out of an explorer but I am not to sure. Google TRZ motorsports and email them I am sure they will let you know more about it.

I've heard of people using 8.8" Fords for two reasons: Price and weight. Its more and more expensive to get a hold of a 12-Bolt these days and a Ford 9" weights a lot more than an 8.8". Also 8.8" rears are in everything. After about '91 or '92. All 4.0L V6 Rangers and Explorers run them. And they ran 4.10's with Limited Slip from the factory. Not to mention you can snag one at almost any junkyard for a couple hundred dollars, if not less. And the newer ones they run in the '05-'07 Mustangs are 31 Spline. Those things are bulletproof in a stang, so I'd imagine they'd do good in a GBody. I'd have to check width. I know the Ranger and Explorere 8.8" are not as wide as the rest.
