If you only want ac, the cost is about $70.
I've ordered one of these. Fittings are #8 and #10 o-ringed (standard sized aftermarket). I expect the heater will require a shut off valve, either cable or vacuum controlled and a second switch controlling the ac clutch relay.
The only issue is there are no provisions for a ducting (for the defrost vents) or outside air intake (again, for effective defrosting). I'll be making a fiberglass cap to fit over the intakes for an outside air tube and an outlet for a defrost connection and a way to block it.
