I'm not sure of the answer you need but generally convertable frames are heavier duty frames. Hopefully someone knows for sure.

With General Motors cars the frames are fully boxed on the convertible models instead of using an open "C" channel. On cars without a perimeter frame like the Camaro they have auxiliary frames bolted to the unibody (kind-a like aftermarket sub-frame connectors) but these bolt to the transmission tunnel of the floor boards which are different than the hard top models with extra ribs in the sheet metal.

Just make sure it is a boxed frame. 65-68 fullsize Chevy's will work. Also on the rear end, if you have 2 top trailing arms that connect the rearend to the frame you most find a frame with 2 trailing arm mounts or cut the mount off your old frame and bolt it on to the new frame. Most base models and 4 door car have 3 trailing arms not 4 like performance models (big block, SS, Caprice). If you plan to switch the frame yourself let me know. I have done several frame swaps on GM fullsize and can give you some tips.
