artist/engineer Jon Stevens wanted to make something cool and unique for his office wall, and decided on a one of a kind replica race car period correct door that looked like it came directly from a team's spare parts

Then people caught on and commissioned him to make them one, now, he's in business creating and selling these hand formed aluminum panels - riveted, painted and decorated with the appropriate decals, mirrors, and latches as if it came off the original car.
