hey everyone, i have a bone stock 4 banger 90' coupe and a 88 coupe that was originally a 4 banger but converted and made into a race car i was ganna swap a bunch of the parts off the race car onto this fresh coupe and build it instead...i was planning on doing the rear end to start off with i was ganna take the 8.8 from the race car and put it on the new coupe to replace its stock one...i kinda have an idea of how to do this but ive never done it and i was just wanting some advice or how to's to make me feel even more comfortable when doing this for the first time and so things go smooth....wat kinda tools do i need? what do i all need to disconnect to make the rear end drop outta the car? Also how difficult is it to do this and about how long does it take....Also when i take the 8.8 out i was thinking about giving it a good paint job before reinstalling it how should i go about this for a quality paint job and what kinda of paint do you guys recommend for this area on a part?
id appreciate all the advice
thanks,
Tyler
