Got a new DenRay hitch but found that the muffler bolts don't look to be long enough to mount both the hitch and muffler. Removed one side and tried the hitch mounting there but looks like I need to get longer bolts, by about 5 mm at least. The factory mount bolts are 50 mm long and have 1-2 threads showing (maybe 2 mm). The hitch mounting there is a firm 5 mm thick. I was thinking of just leaving off the 3 mm washer but that is really needed to keep the rubber insert for the muffler mount from pulling through. The instructions that came with the hitch says to "Take off the rubber shim to install aluminum braces, put them back after installation." What rubber shim?
Any one else with the DenRay hitch needed longer bolts?
