Gary-
Most of those heater valves the big 3 used are made by Ranco and the essential mechanisms are similar. While the kits may now be hard to find the fellas that rebuild them are not. Hemmings lists several. I use Fusick Automotive, a BOP parts supplier with an on site tech who does these valves. He did my 61 Plymouth so he can do yours. Fusick: 860-623-1589
