68mm OD / 62mm ID Roundel?

[netcsk]

I have some Hartge wheels. I don't want to run the full center caps, but I'd like to run some caps to cover up the openings that show the hubs.
I measured them and they are 68mm OD and 62mm ID.
Does anyone have some recommendations? I saw some on ebay, but they are only the "carbon fiber" ones. I'd rather have some OEM that are possibly this size. Anyone know a model number/the car and wheels they go on?

Thanks guys!

Nevermind guys. I didn't even think to check the e39 first, but those caps fit perfectly. Now that I put them on and looked, I'm not sure that I like them.

Hah.
