I have the 18" polished Bullitt wheels on my '06. I ordered the 2 1/2" centers from American Muscle, and they were too big. The suggested I order the 2 3/8" centers, but they couldn't tell me for sure if they would work. Anyone know what centers I should order? I want plain chrome center caps.

 

The OEM Pony caps from my polished 18" bullits measure 2 1/4".
I'm guessing the 2 3/8" will be too big as well.
