Driveshaft Question: Installing Chevy 12 Bolt & TH400 in 70 Cutlass
I am installing a Chevy 12 bolt and TH400 in my 70 Cutlass. I will get the conversion U-joint.
Does anybody know how much the driveshaft will need to be shortened or length of new driveshaft. Currently TH350 and O Type Rear in car.
I would like to have it ready when the swap was made instead of measuring and having it made and thus waiting for the new driveline.
