So i have a 99 formula. and i just got a ta rear end out of a lt1 car with a 3.42 gear. im wondering what i need to do to get that gear out and in my rear end. or put my axles to the wheel on the old one.

In the long run, i need that gear to fit on my c6 zr1 5x120.65 rims. the adapters wont ever fit so i know the rims wont.

it might be easier to just swap the whole housing unless the the TA rear is shot.

Turnerd89, You would get more help if you didn't use metric dimensions. 120.65mm=4.75 bolt circle. Check out this link from Mr. Shoebox about fitting late wheels on a earlier LT1 cars rearend.

thank you for that. although I got some tools took the rotors off and found that out. the ls1 wheel adapter needs to be bored out a little bit.
