1964-65 Corvette idler pulley
 

----I have an NOS never bolted on an engine idler pulley assembly. Looked on E-bay to establish a price and theres one on there for $400ish used. Would sell this NOS one for $300 plus the ride. Good for 350hp, 365hp, and I believe 375hp fuelies. Its a bit dirty but never had a bolt tightened down on it and spins freely.......Bill S
