I bought some corvette wheels for my camaro that did not come with center caps so I bought some for them but they do not lock on to the rims like they should. They fit the rim fine but the inside part of the center caps that lock on the rim dont seem to be the right size or something. I dont understand why they do not lock onto the rim because they were listed to fit these rims. Here is a picture of the rims on my camaro and the center caps.

 

Are your wheels OEM Corvette wheels, or aftermarket reproductions?

 

The wheels are OEM Corvette wheels. I am not sure if the center caps are OEM.
