Alan,
Calnaga Castings specializes in high quality 1:25 scale model car parts. We have several categories that include High Performance (carbs, blower, fuel tanks, valve covers, etc) Powertrain (4x4 conversions, differentials, transmissisons), Marine (jet drive, boat seats, marine battery), Tires, and Miscellaneous. We focus on scratch built masters or kit parts that have been enhanced for detail and buildability. We avoid parts that are already on the market and simple kit knockoffs.
Regards,
Steve Perry
