8.8 rear January 03, 2013, 08:24:00 PM I have the possibility of getting an 8.8 really cheap (basically nothing), its out of a 92 mustang. I know its narrower, and i was wandering what is involved with making that fit, and whether or not it is worth it. Quote Selected

8.8 rear Reply #9 – January 06, 2013, 06:28:22 PM Not entirely. The older mk7's did have 7.5's. I ran across a diesel mark at a junkyard once it had a 7.5 Quote Selected
8.8 rear Reply #10 – January 07, 2013, 01:53:18 PM I have a Mustang 8.8 in my '83, axles and all. Bolted right up and I like the narrower rear as it was much easier to fit my 17 X 9 wheels. All of the 8.8 housings are the same from 87-98 in the Mustangs. What changed was the axle length in 94. The '99 - 2004 housings are a little longer as are the axles and the housings are completely different in 2005+ cars.If I can make a suggestion it would be this, get the '92 unit and sell it to make some $$. Then go and find a 94-98 GT rear with disc brakes and be done with it. Five lug, rear discs, correct width, and you can upgrade to the Cobra rear discs for about $200 with new parts.Darren Quote Selected

8.8 rear Reply #12 – January 12, 2013, 11:31:11 AM So you guys are saying a 87-93 mustang rear won't bolt into a 88 tbird? I just got a fully built one for $250. Was planning on running it in my car Quote Selected
8.8 rear Reply #13 – January 12, 2013, 11:52:23 AM It will bolt right in however it will be approximately 3/4" narrower on each side than the stock axle housing that came with the car. If you use an 8.8 out of a 94-98 GT Mustang it is the exact same width as the stock axle housing that came with the car. The 8.8 housing itself from 87-98 Mustangs and 87-88 Thunderbird Turbo Coupes are the exact same housing. The difference in the trac widths in the Mustangs is the axles on the 94-98 cars. They are 3/4" longer on each side to compensate for the ABS exciter rings.With that being said, you could simply remove the Fox Mustang (87-93) length axles from the $250 rear end you are going to buy and simply install SN95 Mustang (94-98) length axles in the same housing and it will be the correct width. Brakes and bolt patterns are another topic but It has been covered here several times. Darren Quote Selected
8.8 rear Reply #14 – January 12, 2013, 12:03:53 PM Quote from: vinnietbird;406146Use the axles from your Cougar in it. I don't think you can do that cause the tubes are shorter. I think I tried that and when I got it all together it the axles were sticking out and couldn't get the drums back on. I put the stang axles back and I did swapped the 9" mustang drums for the 10" cougar drums on the 3.27 mustang rear I have now. Quote Selected
