Here is the coolant overflow tank from a '64 Galaxie 500 with the 390 FE motor.  I understand this is correct for '60 to '64 Ford and Mercury full-size models with the FE big-block.  Looks to be in good condition, with no sign of corrosion damage, but since I haven't pressure-tested it, it is being sold as-is.  The only damage i can find is a tiny ding (1/8" wide or less) at the one corner.  Is of brass construction and has been chrome-plated.  The chrome is good and shiny and pit-free on the top and where it is most visible when installed, but is not good on the underside and back.  Buyer to pay $20 shipping in the US.
