I removed the logos from the centre of each of the Bowling Ball hub caps gently with an sharp hobby knife, then scrubbed off any glue residue with a little Goofoff, then washed each hub cap. Now they are ready to be sanded, primed and repainted. I'm still not sure if they will fit the after market rims I have, it's kind of hard to tell just by looking at them. Like I say maybe there is some kind adapter out there, don't know??
