Re: 4th gen rear end
you only need the rear end and the same offset wheel as a 4th gen,you will need E-brake cables from a 90-92 disc set up,if you use an Ls1 rear you will need to fab your own e-brake set up.i used a combo of 3rd and 4th for my TA

Re: 4th gen rear end
You need a jack, pair of jackstands, sockets and ratchets (impact makes it much easier), PB blaster, 11mm wrench.

Re: 4th gen rear end
thanks for the help... but also some of the rear ends come with traction control is there any way to by pass that or just up and eliminate that all together?
