2009 Chevy Cobalt hub cover caps.

I have a 2009 cobalt xfe and want to do something inexpensive to make it my own. I want to take of the hub caps and paint the oem steel wheels metallic black and put a chrome trim ring on it with chrome lug covers and chrome middle cap. I am having a problem finding the chrome middle cap. Anyone no where I could source these?

THANKS!! I believe this will answer my questions. I just need to measure the opening now.
