Help--I'm trying to stop the confusion in my own mind. If the overall max. length and width dimensions for the 56-58 frames are identical, what exactly is the difference in the frames over those 3 years? I know '58 went to a bumper-to-frame attachment where earlier it was bumper-to-body, but I have a '58 sitting on a '57 frame and I'm wondering how the '57 vs '58 differ? Thanks in advance.

Re: 56-58 frame differences
Steve--extremely minimally. I think you've hit on the primary difference--bumper mounting. No change in front or rear suspensions--both mount the same. Battery tray is identical. No rear stbilizer bar or radius rods on either. Exhaust routing is almost identical on the body and certainly through the frame. e-brake no changes. engine and transmission mounts are the same. Radiator support and shroud are unchanged. Hope that helps.
