Can I get some EXPLICIT steps on doing an AC delete?
 
I've been trying to get a solid answer online and have had no luck.

My '78 K10 came to me with the outer heater box completely tore off. The only thing still there was the blower motor and housing.

I want to run heat only, no interest in restoring the AC (if it ever existed). The controls in the cab do show AC selections so I am guessing at one time it had it.

I have seen aftermarket "AC delete" boxes which appear to just connect the blower motor with the large square door in the firewall. I am in the process of fabbing my own to save money.

Is this job literally that simple? Does it require any modifications inside the cab?

Pic of my firewall. Any help/advice would be appreciated!

If you're going to run a heater core the lines(tubs) are in a different place then the A/c lines. Weld in the big hole move the tube closer to the big hole.
Go wrecker 77-80 remove the non-A/c heater housing under dash and engine bay and heater core fire wall wiring resister and the heater temp switch and the wire rods for the flapper doors.

This is a none A/c fire wall see the difference. If your not going to put in a heater core just weld both holes. no heat for in the truck or for the windshield early morning or late-night drives.

Thanks guys. I finished this up over the weekend, replaced just about everything including the wiring.
