To the good people of JKO, would anyone know of the size that the centercaps are on factory non-rubicon 17's? I can find the caps themselves but no where have I seen the size, I WILL NOT PAY the $9 each that the stealer wants for them so I'm looking for other alternatives. My jeep had the 16's on it new and I got these wheels off of craigslist without the caps and put my 35's on. I've already tried a couple junkyards to no avail, Jeeps in junkyards here are few and far between. Thanks in advance!
