I think Boyd Coddington made the wheels for the black car.If I had the money,space I would build a convertible ZR-1 just because there are only a few out there,most private conversions.How Id do it Id use a ZR-1 and a convertible,same years.Strip both cars from the B pillar back and use ALL of the convertible structure piece by piece.I wouldn't just lop the top off the ZR-1.
