Couple questions about heat, and deleting A/C

[Scott76]

My truck is a 79 C10, bought it a few months ago. Barely had it running before I tore into it and this is my first C10 so I'm ignorant as to how some of the symptoms function. It had about 1/3 of the A/C system there when I got it, and that's fine because I don't want A/C anyway. I live in Wisconsin so it never really gets that hot, I like the windows down fresh air, and most of all I like the simple, clean "less is more" look. I'm not worried about the engine compartment right now, but I'm getting started on the interior and would like to eliminate the A/C ducting, vents, and controls. I found a non-A/C control panel locally on CL. It's from an '83, I assume that will work? What vents are for A/C and which are for heat? From what I've gathered they are completely separate? I was temped to eliminate heat as well, but it really doesn't gain me anything to do so and I would like to retain defrost, at the very least.

One thing to keep in mind is the heater box and the hole in the firewall are different

Yep. Further down the line I will get a non-A/C blower motor and weld in some sheet to cover the hole left by the A/C.
