Fella"s are the crank and water pump pulleys on 63.64,65 & 66 401 & 425 Nailheads all the same size. If they are would those bright shiney ones (chevy) in the Old Dogs Street Rods shop here in St. Louis have a chance of fitting my 65 401 which came without puleys. Thanks Al T.
a/c and non ac pulleys would be different. I don't think chevy water pump pulleys are the same... and I know crank pulleys are not. March makes pulleys and so does Russ http://nailheadbuick.com/dampner ..
