Trying to keep everything tight, I noticed what I thought was a loose bolt for the large rubber bushing between the frame and body under the passeger foor area on my 76. I tried to tighten it and it spun freely. I got to the top of it but cant tighten it. What kind of problem will ths cause? It has quite a bit of play. Looks like a pain to deal with. Thanx--
the plate on the frame could have rusted through. you can weld in new metal on the frame and fix that. And if the bolt turns free, the welded nut in the floor pan came loose and needs to be welded also.
