I need the truth about wheel adaptors

You will need the complete rear end if yours is a 7 1/4, upper control arms, spindles, calipers, backing plates, rotors, master cylinder and a disc brake proportioning valve to start with.

If you change to some rear end different than your car has in it then you will need a drive shaft also. I wouldn't waste my time putting in another 7 1/4 if that is what you have.

If you have the 8 3/4 then you will need backing plates, all brake parts, drums and new axles made.

I have a 8 3/4 diff. I did not know it took that much changing. Sounds like it might be cheaper to go with something like 68383gts. They look really cool. (changed my mind again) I think I still like the ones that look like the old style keystone torque thrust, personal choice. I got his link from tool man mike. http://www.team3wheels.com/classic_v.html Just need to find ones that look like them just a little cheaper
