I mostly duplicated the original factory layout with both hoses and hard lines to look as close to the original as I could with the modern fittings and components. Hoses I made to fit but there is one run of metal tubing along the vent tube in the engine compt and a couple of lengths inside the evaporator box because of the modern evaporator core. Instead of copper tubing, I used stock aluminum lengths with rubber O ring fittings ordered from Vintage Air.
Receiver/drier is under the radiator splasher where the orignal was located but is in a different style can so made a different bracket for correct positioning. The different configuration also required a change in how the tubing was laid out. Also added a binary over/under pressure switch to protect the compressor which the originals did not have.
Thermostat is a cable operated unit that I mounted outside on the end of the evaporator box. Apparently I did not take any detail photos showing it mounted since the one I could find only shows a tiny bit of it. It is connected to the temp lever by a short Bowden cable. Made a small grommeted opening to run the sensing tube inside to the evaporator core. I had to make a second mounting stud and clamp position for the extra cable to attach to the stock temp lever and housing. Temp lever still works as original for the heater as nothing there was changed. Moving lever down still provides more heat. The AC thermostat mounts on another area of the lever and works just the opposite. Full cold when lever is up and off when it is down.
I don't remember the model number of the switch but bought it from Nostalgic Air. They only show one cable type now so it was either that one or the one I used was discontinued. If it is not the same one all I can say is you may need to look at several vendors and examine the specs or work with the positioning and cable mounting to the lever so it will work the way I wanted mine to work. I wanted to be able to use the stock temp lever and have everything work opposite to the heater.
