I have an 86 T-bird V-6 auto 7.5 rear. I went to pick and pull got everything from the rear of a 1996 V-6 mustang. When I put it all together everything bolted right up till I got to the axles. First the axles would not go in all the way because they step up where seal rides. I removed the seal to continue test fitting and with the axle in place it's off by .750". When I went back and made some measurements to get the rotors centered in the brackets I need .750". It looks like I need 99-04 axles for this set up. I just ordered new ones from Rock auto wish me luck. Any info would helpful.
