recently my car hit a curb a bit too rough when i was leaning down to grab my cell phone. stupid, i know and now i have a split hubcap. i could just go get a replacer from ebay, junkyard, etc. but, i always hated the hubcaps on the car anyway, so im curious, just how universal are hubcaps? say, i have a '98 mustang, but i have an '05 taurus. or even different makes, like a 15" chevy cavalier. are all 15" rims, for the most part, able to be swapped around, so long as the valve stems dont get smashed? i would at least think that all fords would match up, chevys would match up, etc.
