1994 8.8 in pre-93 GT. How well does it fit?

So I may be able to get a wrecked 94 GT for $400. Not only can it be a parts car for my wife's 95, but I need the rearend. I know the 94+ rearend is approx. .75 inches longer on each end but how much does that affect clearance. Has anyone bolted one of these into there car before? Does it rub or are there any other problems? Is it mandatory to run special offset rims? Thanks in advance.

sweet, though I think I may have to stick with the GT brakes instead of using the Lincoln brakes I got. If you've seen the site, you can see that they are designed to be "fixed" so they take out the 1.25 extra inches from the lincoln rear to the mustang rear, but now that the 94 8.8 may be used, I think it may throw all that out of whack. It may be best to just go with my plan to get ProGear to supply the rear for me because either way I need to throw my built axles and Auburn in it. And I cant use the axles I bought already for the 94 rear for obvious reasons, and the auburn is for 31 spline, so I cant use the stock axles. I think I may just buy the car for parts and leave the rear in it or as a spare. This way Ill have a good 7.5, good 94 8.8, and the one Ill be using in my stang.
