Does anyone know what this is? When I had to remove my fuel tank, this was inside one of the frame rails. I am not sure if it came loose. I didn't see the other end. It may have been trapped there...
I vote body bushing as well. I once found a pair of vice grips clammped underneath my car. When I replaced the roof my on fiver I found some magazines of the vintage my trailer was. They were laying on top of the insulation under the roof.
