Thought I'd update on the AC.
With the RUF style bumper, I was able to bolt on a decently sized 10x18 condenser in the front to get good airflow along with a 9 inch fan. The opening in the bumper helped as well. It was a tight fit but it fit nonetheless. I routed the hose through the frunk and bolted the drier inside as well. I kept the original denso compressor as I was told it had good capacity. On the drier I used a binary switch which triggered the compressor clutch, the cooling fan relay, and sent a signal to megasquirt to open the idle valve a bit more to compensate for the drag of the compressor.
The vintage air unit works by recirculating air from the cabin so I had to keep as many openings between the cabin and frunk as possible to make it one large space. Otherwise the unit would be working double by picking up hot air from the frunk, cooling it, and sending it to the cabin. This way, the entire area is cooler, so the air going through the evaporator is cooler to begin with. I ran the refrigerant lines going to the compressor through the old heater duct in the rocker panel to protect them road debris and a cleaner look. With the lines hooked up I charged the system r134a and tested it out. The tune bumps the idle up smoothly and immediately however there is a noticeable difference in power with the power on or off.
Most importantly, it cools! We're already in the mid to high 80's in Miami and the AC keeps me cool enough with the windows up that I actually had to turn down the fan speed while driving. I should add that I was worried about the greenhouse effect all that glass would have so I had ceramic tints put in in the lightest shade possible. The addition of AC makes this car much easier to drive on longer trips or trips where I might expect heavy traffic, especially in summer. I can't speak as to the accuracy of this old thermometer, but it shows vent temperatures between 32 and 35 degrees fahrenheit pretty consistently. I've put about 1000 miles on with the AC in place and no complaints so far.
The vintage air unit has a heater core inside as well that I was told would accept oil just fine. If I find a safe way to tap into the oil lines and get oil flowing through it I might consider it to have working heater for the rare cold day in Florida.
