Eh, looks all out of proportion with the chopped top. "Why who put this '69 'Cuda roof on here?" I would dig it with a targa top though, and ditch that back side window.
With the exception if the VW Beetle (and maybe tri-5 chevy), you can't really chop the top on anything post '54 and it look decent. I know I've seen an A-Body with a chopped top, but I couldn't find the pic.
