I posted this here because Diesel is my home
and seems to have more readers tuned to what we do.

I want to know what size wheel center caps are used on the
1980's 14 inch alloy wheels (bundt).

I measured mine and they are about.... 3 inches.

When I do the mm I still am not confident as to what size they are.

I know it's a stupid question, but so far I have collected and paid for
every wrong size.
