Trying to figure out the rear cab mount on the 47 3/4 ton.
The center mount is an obvious rebuild with the new bushings but the outer mounts are gone except for a few flakes of rust. The new teardrop bump stops have a 3/8 mounting bolt which is different than what was removed. The rebuild kit is from Classic Parts.

Do I need to fab a new bracket to mount the bump stop or do I drill a hole in the cab floor to mount the bump stop above the frame? How much clearance should there be between the fame and bump stop?
