I bought a set of the Challenger door handles. They are nice pieces! Didn't buy mine from megaparts, mine came from Joshs musclecar parts. Regardless there is probably only one set of tooling for the repros and many suppliers. Not sure who is making these, might be Dales Cuda Shop as on the back side of the handle a small "DCS" is cast in. The handles fit great, they come with a rubber gasket, while not correct, the gasket fits the handle better than the original plastic gasket did. The handle also sits even with the lock portion. The originals never were even and sat slightly below the lock portion. While not an exact copy of the factory handles, dare I say they might be better. The fit and finish of the repros are likely what the factory likely was going after 35+ years ago.
