Thanks.
So my plan is to keep running R12. Since the compressor was upgraded.
The previous owner had the system charged but the line from compressor to evap leaked. It looks like there is a newer hose from the compressor to the condenser in the rear.
I figured I’ll make up all new hoses on the car with crimped ends so that I can run with the slack that I want. I’ll also replace the drier then get it charged. That coldhose.com site looks to have a good selection
Realistically, in New England, I’ll probably use AC less than 5 times a year. The heater gets a work out though.
