After seeing a unrestored survivor 64 1/4 car at the MCA show last week I identified these in my hardware boxes . Since I don't have any 64 1/2 I thought someone wanting original hardware might want them. Fine thread flange head bolts used to hold the radiator on a 64 1/2 to the radiator support. 30.00 shipped to US address. PayPal friends and family only. PM with any questions.
