If it wasn't for the fact that your lug bolts are so far gone, I would suggest getting a set of cover/caps to place over the bolt heads . Believe it or not, they're simple to use and they look good. On the other hand, there are other sources that you can pick up a set of high quality spacers for much less money . In fact, a good person to ask is no other than Mr. Littlefield himself (aka The Grand Poobah of New Paltz) . In past, he found a seller on eBay who was offering some nice spacers for cheap .
