Heat/air restoration

I have a 66 fish that I have stripped down to paint black. It has a black interior and came with no heat/air system at all but is an air car orig. It had all been removed to make a race car before I got it. It only has the drivers vent inside. It is beginning to look nearly imposible to find an oem system for my car so I am thinking of using an afternarket set-up.
Any suggestions or pics of how you did yours would be of great assistance, I am not going w/out air in a black car and I trust you guys in showing me the right way to go. thanks
