The hardtop frame will have one additional body mount bracket on the inboard side of the rail right at the B-pillar. If your using the hardtop frame on the sedan, just remove that bracket. If you putting a sedan frame under a hardtop, switch the bracket fron the hardtop frame to the sedan frame.

’55 & 56 frames are identical except they have different rear spring hangers. ’56 has a small gusset welded into the rear box portion on each side.
’57 frames have different front horns for the bumper mount. I don’t know about the rear spring hangers.
Convertible frames have an x-member welded into the middle for stability.
Hardtops have the extra support as noted.
Some frames are ‘one-piece’ and some have welded seams but are identical mechanically.

A ’56 2 door will fit on a ’55 frame for a four door, etc. All years and styles have the exact same wheelbase. 115 inches.
