Goodmoring Chris,
I'm looking at these center caps and I have, it looks like the one I mentioned with the 0924187/23 42 and three with the same number only adding another 2 at the, so they read 0924187/23 422.
My spare is a 94 15 inch, but these center hubs came off a newer 5 series. The person I bought them off, wasn't quite sure of the year though.
Hey are those your cars in the link below your name? Sweet:)
Thanks Chris,
Matt
