Thanks for the help red58! Now when you say they won't fit is that because they physically won't fit in the wheels center opening or is it because there are no clips in the center to hold the cap in place? I found the clips for sale online so I was thinking I could add them to my wheels but if the cap is too big to fit in the hole then that's not going to work.

I was thinking my wheels were post 60 based on looks but wasn't sure. If I can't get the original style to fit what I have I was thinking these might look good.

I believe these are correct for post 60 rims?
