Postby 6475vegaChevy » Thu Jun 25, 2015 7:28 am

I am in the putting a 9'' in my 75 Vega GT,it currently has the factory 4 link,which I would like to change to a torque arm,i have seen different lengths from (stock 39 3/4 to 46 1/2 ) depending on drivetrain (I am using a 350 crate -Turbo 400) what length will work best (plan on building my own) any set up information is appreciated.

You will probably want one of the shorter ones, but you will have to fabricate a front mount for it, as there is no tailshaft for a TH400 that has the mounting holes for the torque arm. I suggest mounting it to the crossmember instead of the trans anyway.
The "fleet"-

00 Saturn SW2- wife's car
01 Saturn SC2- younger son's project

and 3 more Saturn "parts cars"
Note- the very act of listing all of these has made me realize I have some kind of problem.....
