'99-'04 Mustang axles into a 7.5" (Fitment & Feasibility) May 26, 2007, 12:35:15 AM I was thinking about putting some '99-'04 Mustang axles into my '87 7.5" rear end. The housings should be very close or the same in width. Data from Jim Miller's thread shows they're .06" different. Installation of the Detroit TrueTrac and rear girdle should increase the strength enough to live behind a mild 351W sans slicks and drag launches. Does it save much weight or make monetary sense, no. :hick: .On the fitment issue, I'm sure members have swapped in Mark VII rears, but I can't find any threads regarding it. I'm worried about tire/wheel to fender clearance Quote Selected

You CAN build one, have it all, and not add as much weight as you would swapping in an 8.8" rear. Personally I can't wait to see it all done. Quote Selected

'99-'04 Mustang axles into a 7.5" (Fitment & Feasibility) Reply #7 – May 26, 2007, 11:30:12 PM the whole axel will fit fine but the shafts are a no-go in the older housing, i had a rear end from a 01 gt and not only was the housing wider but the mounting for the LCA's were further apart also.
