I have a 1977 280z, looking for a heater control valve, i've checked online sites and auto parts but they say its discontinued. My Z has the control valve mounted on the heater housing not on the firewall, it has A/C if anyone knows where or who i can contact i would appreciate it greatly.

Thanks Silver bullet Z

Check your local Nissan Dealers Parts Department?

I don't think Nissan has them for 280Zs any more. At least, that's what Z Specialties (who offers rebuilt units on exchange) claims.
