This is an NOS 15" Buick wheel for early sixties, late fifties fullsize cars. The bolt pattern is 5x5 and the center hole has a 3" diameter. This wheel has never had a tire mounted on it and other than being a little dusty appears as new. Good to have for a spare or replace a badly rusted wheel you may have on your vintage Buick. Get this for your 58 59 60 61 62 63 64 Buick Electra 225 Invicta Wildcat Riviera Le Sabre. I also many other 60's vintage Buick parts available including Skylark and Gran Sport parts. Thanks for looking and good luck bidding.
