I slid the doubler under the truck to get a feel for what my rear driveshaft length and I think my high angle shaft will work without shortening it.
So far the only problem I have ran into is with the new trans, the trans mount on the trans adapter doesn't rest against the old trans mounts on the factory crossmember. Does anyone know if chevy used a different crossmember for the later model standards? I think I have a crossmember from an auto in my shed so I am gonna try that first or build a new one.
Also, what angle are most factory drivetrains set at, or most of the 4x4 builders using?
