I recently purchased a 93 Ruby and have ordered new wheel center caps because the one's I got with the car are faded.  My question is, do you have to remove the wheels to replace the caps?  I don't see an indentation or other means of doing it from outside.  Loving this car and just want her to look beautiful!

Easiest to pop off from the inside out, with the wheel off.  You may damage the wheel if you try to pry off from the outside.

I thought that would be the case. Thanks!
