alright guys... laugh at me. A guy i kno wants me to put a set of gears in his 8.8 mustang rear. iv never actually done a set of gears before. my ford 9" was just a third member i bolted in. anyone have a how to on this? and hes not a friend nor a buddy of mine. saw my truck and was like hey stranger you wanna work on my slow stang? he says he has the gears and install kit with shims.what should i charge him? is this a difficult job? should be pretty straightforward if i just reuse the old shims and just check with the marking paint?
