Hi. Trying to install an R&G radiator guard to my 401. The star-head bolt to the left of the horn will turn a bit, but not unthread. Turning it either way feels like it is bending/tensioning a piece of metal, and after turning a bit, the bolt will pop right back into place if I take the tool off it.
Because of the rubber mounts, I can’t even see what the problem is. Any ideas? Thanks in advance.
