I found a cool pair of center caps on eBay. So for $18, I thought I'd try them.

They are advertised as 59mm, and they were a hair small. They snapped it but clanked and spun, so I did a wrap with a thin piece of duct tape around the back and they seem to have popped in ok (electrical would probably be better but could not find my roll).

Anyway, the OEM R caps are the before and the black/slate union jack are new.

 

Those new ones look way better. Nice find!

 

I do like those better than the "R" caps. Not a bad price either.

 

I like those!!!
