The radiator shell on my '46 1/2 ton pickup mounts to the front cross-member with two carriage bolts through square cut holes in the shell, through a soft pad and shims, then on the under-side of the cross-member each bolt has washers, a coil spring and a nut. The restoration parts houses sell new shell mounting kits that have much shorter carriage bolts and on the underside of the cross-member they have no washers or springs, just a lock washer and nut. I have heard both that the longer bolts and springs are original, and that they are not original. Anybody have an idea if the longer carriage bolts with springs mounted under the frame are original or not?
