@#$%&*!! back rest

[farm1810]

I bought and after market, Harley tour pack and the back rest offered by the manufacturer. The back rest has brackets and the lid needed to be drilled for the back rest brackets. Okay, have that. Between the back rest bracket and the bracket that bolts to the lid, they provided a rubber insulator. This turns out to be a rubber bushing of about 1 " in length with the head of a bolt embedded in each end, giving threads sticking out each end of the rubber bushing. The problem is, I haven't even finished my mounting bracket for the bike and the bolts are popping out of the rubber already. What does everyone use? I considered a piece of all thread in each of the three locations, with jam nuts on each side of the bracket. What have others done for this?

You could try something like this http://www.mcmaster.com/#vibration-damping-sandwich-mounts/=htfyuz

If you need them to seal to the tour pack you may need an additional rubber washer or gasket to seal as these appear to have metal faces on them.

Most luggage racks use a flat stainless washer, and then a thinner rubber washer for weather seal, and the mounting screw comes up through the underside of the lid with the same set up in reverse. A 1" studded washer seems to be excessive.... If what you are saying is what I think you are saying??
