Nothing on the controls just yet, which I hope doesn't bite me in the end.. I picked up the A/C dash control from the junkyard which has the wiring plug with it for the A/C on-switch, and I have part of a spare harness that has the cycling switch plug, and part of another harness that has the compressor plug. I have some nice aftermarket relays with harness/plugs from a previous project that I never used them on. 40amp relays I believe. I need to go pick up a fuse holder or two locally.
I still have to order the new evaporator, hose fittings, hose, new cycling switch, refrigerant gauge set, PAG46 oil, accumulator, orifice tube, Nylog, and charge port R134a retrofit adapter.
I also need to measure for a serpentine belt.
I plan to try the super cheap Harbor Freight compressed air powered venturi type vacuum thingamajig. It's got good reviews. It'll work my compressor pretty hard, so I plan to do it in cycles. I'll put a large fan blowing on the compressor, run it for a set amount of time, monitor the temps on the compressor heads, and give it regular breaks while shutting off the manifold gauge set valves to maintain vacuum.
There just isn't money in the budget right now to buy a nice vacuum pump. It may be a redneck plan to try this thing, but it's cheap, and I won't be adding refrigerant through it: https://www.harborfreight.com/air-vacuum-pump-with-r134a-and-r12-connectors-96677.html
