1967 GM Rally Wheel Center Caps

[Mr. Chevy]

Does anyone know how the GM Restoration 67 flat rally wheel center derby caps compare to an NOS Gm set?? Any cosmetic differences, fit/finish etc....????

Thanks Rich

GMPD service caps were not the same as OE. On original caps the retaining ring was painted black; service caps were galvanized.

GM OE and service caps were polished stainless. The aftermarket caps I have seen are chromed.
