Gwen, Both clamp types are pretty easy to get. AMC wasn't the only one to use them. I know Kennedy American carries them and I'm sure a lot of other AMC (and non-AMC) restoration suppliers have them as well. The heater hoses may be a mixture of 5/8" and 3/4". I don't know about 1964 hoses but in 1968, the hose had a yellow stripe on it. I can't tell with great certainty from my pictures if there are any ribs or not but the hoses appear smooth. Also, I'm pretty sure AMC used Gates hoses but the modern markings look nothing like they would have back in the 60's. If you end up with a contemporary hose, you can clean the modern looking markings with brake cleaner (spray the cleaner on a rag, not the hose) and follow it up with something along the lines of Armor All to get the shine back. The valve assembly you're referring to is the heater control valve. It goes inline with the return hose. If you can control the temperature, it's just somewhere else on your car. Matt <snip> 1.
