Re: Back Space Question
Not sure on the rear end widths, but if the new rear end is a total of 1 inch wider (axle flange to axle flange) and it is centered in the car!!--you should need 1/2 in more backspacing in your wheels for them to be in the same place as before!!
I would be careful about the second post, because your front wheels (with less bs) would look deeper than your rears!!!! Thats why I would run a 7" on front with 4-4.5 bs, and then the 8" on rear with 4.75bs. It will work fine--we do it daily!!
I used to have a link to factory rear end widths-but I can't find it. Do some poking around on the net and research the widths!!
