I'm hopping someone knows how to get this thing working again. I have a 74 260Z without A/C, and the Heter control valve just broke. MSA says that they can only get the version with A/C, which won't work. Mine is a simple cable driven system with no vacum lines or elec. controls. I looks like the lever controlled by the temp mixing switch operates a "plunger" in the valve. There is a "stem" sticking out the backside of the valve, and it looks like the lever had something attached to it, but I can't find it.
Am I right to assume that there was something connecting the lever to the "stem"?
Does anyone know how this can be repaired, or do I need to hunt down a new one?
Or does anyone have a good picture of what this part is suppose to look like?
