hey guys. I have stock axles d30 and c8.25 with some crager soft 8s 15x10. I'm looking to get some center caps to cover the gross looking hub showing through the rims.

crager said i needed this part:

however, they're $12 plus $6 shipping each. I'd rather pay $10 through prime for a set of 4 pos chinese flat caps rather than that. They're all going to get ruined anyway.

What size am I actually looking for?

Edit: I see it says center bore 3.3 inch, but that comes out to 83mm, and i've read we need 71.8mm but i havent seen anything at 71 nor do i know why crager would tell me i need 83 if that was the case.

 

The easy answer would be to measure the hole in your wheel. I used these center caps from summit on my wheels. link
I think 3.3 is a standard center cap size.
