If your brake pedal is rubbing it is most likely that the cab has shifted if the floorboards are weak or rubber bushings have failed.
Yeah, I was wondering about this. How tall are the stock rear mounts supposed to be? I had a 78 Silverado that had mounts that were about 1" tall at the rear of the cab. The doors were far from smooth when closing. I found out eventually that the mounts were supposed to be 3", and we're severely squished! New ones made a big difference.
Anyway, the rears on the '55 are probably still a couple inches. I didn't see any rubber at the middle mount at the rear of the wheel opening, however, and thought it was strange. Should it be steel on steel here? Seems wrong...
