About 10 years ago, I had this same problem with my '72 Coupe. At that time, NAPA sold a manual heater control valve in which the bottom section looked just the servo controlled Auto Temp II, but the top half had none of the controls or the servo motor. I DID, however, have that seal, all new and pliable, in there. By dissassembling the new NAPA unit, I was able to reseal my old Auto Temp II unit. Try to get the folks at NAPA to allow you to look through the pictures of their heater control valves. You'll see one that has the same bottom end as the Auto Temp II unit, (if they still have it).
