The Club website shows the following NAPA number for the "Heater Valve Repair Kit " : 660-1000 On the Club website that number is shown for 1957, 58, 60, 61, 62, 63 and 65 300's. I would think that the years 59 and 64 would use the same kit. Good Luck !!!

The control valve is in the heater area and leaks on the passenger side carpet. The valve is located behind the glove box. NAPA sells a repair kit for the valve for about $10. I repaired my valve a few years ago but haven't installed it yet. I shut off the antifreeze to the core and I seldom need heat in Georgia.

Can these cores be repaired or must they be replaced. If it has to be replaced, any sources for this part would be greatly appreciated.
