Help! 7.5" Axle to 8.8" Trouble! Reply #63 – January 23, 2008, 01:17:49 AM Just an idea.What about swapping the tubes?No bracket or length problems.Ask around, someone where you live should be able to swap the tubes and maybe even square them up and weld them in place...I have acquired an 8.8 differential with a powertrax posi unit. My issue comes from the fact that the axles are 5 lug and am using 4 lug rims which I do not want to replace just yet. Quote Selected

Help! 7.5" Axle to 8.8" Trouble! Reply #66 – February 22, 2008, 03:47:10 PM So does anyone know the width of the housing in an 84'-92' Mark VII? Im going from a Fox Mustang 8.8 drum rear to Mark VII axles, rotors, calipers, ect. Im looking for the 5 Lug vented rotor and the extra width. Just want to make sure its going to be a bit wider then an 87'-88' Turbo Coupe rear end. Quote Selected

Help! 7.5" Axle to 8.8" Trouble! Reply #68 – May 11, 2009, 10:18:07 AM I put an 8.8 under my bird from a 91 lx with 2.73 trac lok and i ordered 1 1/4 wheel spacers from ezaccesories.com for like 84 bucks shipped. the only problem is they come with 12mm studs and lugs. And the only problem i ran into with the rear was the fact i have air shocks the kicker shocks would have came into contact with them. Also if you go the mustang route get the brackets to bolt the kicker shocks on from the doner car. your gonna need them and there bolts for the frame( some special bolts). Unless your not worried about the kickers like i wasnt. and it only took me about an 1 1/2 to swap rears and get her back on the road. Just what ever you do dont weld the diff in the 7.5 and try driving on the street i did and nothing but bad things happened=] but any other questions let me know Quote Selected

Help! 7.5" Axle to 8.8" Trouble! Reply #70 – November 27, 2014, 10:59:14 PM To add to the chart, my 1989 mark vii housing width measures 54" via tape measure, so I assume it is the same as the others of the same era-54.096. It appears that the only difference is the axles. Quote Selected
