901 Shift Knobs: Reproduction (Left) and OEM Knob (Right)
The reproduction is very nice and very close to the original part, but there are some very slight differences:
The original has somewhat thinner plastic than the reproduction.
The reproduction has a brighter sheen than the original on most. Expected for a 40+ years older part.
The numbers, lines and letters are more rounded on the reproduction and almost flat on the original.
