I realize this is a little bit of a noob question. In any case, I bought some used 18 rims/tires from a 350z for my G35.

They are this model:

I want to put different wheel caps on them. I found these on ebay:

Is this a standard thing? Can I just get these wheel caps and get my tire shop to replace them?

Thanks!
