Not sure I understand the question.
Are you asking what options are available to install ac in a vehicle that never had one?

If that's the question, I'd recommend finding a vehicle at a pull your own part salvage yard and removing the factory system. It's not that bad to do. Take all the lines, hoses, mounting brackets, screws. bolts, and pigtail wiring. Be prepared to spend a few hours. Any 1984-88 RN5 or RN6 should work.
Take the entire evap box under dash. that comes out surprisingly easy. AC on/off switch, too. Compressor is debatable. You might want to consider getting a new reman unit from Denso. But either way, take the service plates off the top of the compressor(you need 6mm hex to take those off). The reman won't have those charge ports. Make sure to take the compressor bracket.
I'd recommend going to EPC Data and printing pictures of the AC system before you go hunting. That'll show all the individual parts you'll need. Most stuff will be obvious, but you could easily overlook certain things, like the VSV on the valve cover.
Denso still offers compressors, condensers, receiver driers, evaporators, and expansion valves at fair prices. So if any major component you grab is defective you can easily get a new one.
If the wrecking yard vehicle doesn't have a Denso system i wouldn't bother with it. Finding parts for an aftermarket system could be frustrating

I’d like to assume anyone salvaging a system would properly clean every tube, hose, and component with rubbing alcohol. Toyota o-rings (90099-14044, 90099-14045, 90099-14046) can be used with either Freon. Whether using a used or new compressor the mineral oil would need to be removed and replaced with the proper oil. I put 2 oz of ester oil in the compressor and just under an ounce in the receiver drier.
I used crowfoot wrenches on my torque wrench to tighten fittings, but doing it by feel works ok, too.

Check on eBay. There's a company called ACKits that sells a $1200 kit for pickups and 4Runners. There's also a YouTube on what parts you need for an '87 Toyota pickup so you can piece together your own kit.
