Try the 4th link on the page for nostalgic air. There are more...
No conversion fittings. Their Sanden compressor has a head cast and machined to mate with the Harrison A6 hoses.

The system already has a Low Pressure Cutoff switch set for R12 pressures.
You'll have to add a High Pressure Cutoff port in the high pressure line. It's wired in series between the low pressure switch and the compressor clutch.

R134 takes more planning and care to do it right.

You'll need to cut out a section of the firewall opening that's large enough to give you a patch panel to install in the non AC cab. Take the fan box off the firewall on the non AC cab and the AC box off the AC cab. Look at both to see how much you need to cut out.
I'm curious... How rough is the donor cab?? If it's generally in good shape you could just swap it to the non-AC truck. It'd take about the same amount of time as cutting up both cabs and playing the welding and wiring game.
No need for a new thread. It'll be easier to follow if it's all in one place.
