Heater delete

Has anyone ever found a heater delete truck in the dentside era with a heater delete? The cars could get them till around 65. Maybe something south of the border? Would like to see what they did with the right side vent. Just curious.

I have never seen a "heater delete", now NO a/c ='s no R/H vent. With a heater only truck, you do not get dash vents like an a/c truck.

Canada was the same as US after January 1968, because vehicles assembled in Canada could be ordered from the US, especially from GA/NC/NJ/NY

These features were optional in other countries.

My '77 was originally a heater only truck, the passenger vent was only a door one could open under the glove box area. Originally, with bug shield, we got next to NO air through either vent (still has driver side vent) ... which was when I robbed two junked donors of their factory AC and spent a week of spare time fitting it all, including that big firewall hole and all the dash vents. Later, after getting it all going, came a day I removed the bug shield, and suddenly my kick panel vent was blowing great at speed. I'm on the edge of jumping into getting AC working again (like some new O-ring seals, drier, exp valve, comp shaft seal, R134a) as it eventually leaked down. Even with the bug shield out there on the hood, AC flow was low.

Point ...I have often wondered (and I still wonder) how well those dash vents would distribute fresh air with NO bug shield spoiling air over the hood so it misses the cowl vents, and with no evaporator core blocking flow (or maybe it doesn't block so much so that it could be left in place?) and the heater hoses turned off or bypassed and/or redirected with a H type 3 valve setup so that the heater core did not heat up. Maybe add some foil type insulation and / or a heat shield between AC housing and exhaust & right head?

Well, they work pretty well. In the spring open the wing windows and open the floor vents and head out on the highway. You will eat all the dirt you didn't clean off the floor.

As long as there's no lima beans in the floor ...

I guess I could "test" the idea, no AC belt, unplug compressor wire, make sure heater valve shuts, or temporarily place a U-turn at heater pipe inlet end of hoses?
