The Stovebolt Site Forums The Shop Area Paint and Body Shop 47-48 Rear Cab Mount Rebuild

I installed the rubber bumper on my frame, but the provided holes are more on the top of the crossmember and getting the nuts on the bottom requires a few choice words. Letter f in the assembly manual. Part of the bumper is on the frame rail which sits higher than the crossmember. I am thinking about grinding the bumper to fit and sit flat. With these bumpers that are circle shaped and same size top to bottom, it puts the center mount up in the air almost 1/2".
Is that normal
