Well I now have a 67 3/4 ton front end to do my crossmember swap into the 61 C30 Panel truck. Needs the usual cleaning and painting and I'll have to see how good the working parts are.
Since I'll be removing the whole front crossmember and the crossmember for the bellhousing mounts is already loose I was wondering about structural integrity.
This is an assembled truck minus drivetrain.
Seems pretty obvious I should leave torsion bar mount in place for now.
I could bolt the B/H crossmember back in.
Maybe a temporary support so body weight doesn't move front of frame around?
Any thoughts?
Thanks
