These hub caps are off a 1991 Mazda Miata BRG Special Edition.
The Number on the Back Side is: NA01-37-190. They are about 5-3/8" diameter.
When I bought the car they had been painted a flat black by a previous owner. I had our local auto body shop paint them silver 12 years ago.
They look great but a close inspection will reveal slight imperfections in the paint job; the painter said he thought the flat black was probably done with Rustoleum which was difficult for him to nuetralize.
Note that the original hub caps are silver with the Mazda name in black.
