I was looking to replace my four missing center caps. I found some online for 49.00 for the set. I believe there a two different sizes. How do i know which one i need. Can you tell with the rim size? Or do i have to measure from lug to lug. Just want to make sure i get the right ones. Also any tricks for keeping this set on. Thanks.

 

all the same, you should have 16" wheels with 5x135mm lugs
