Re: A/C line, condener, dryer components and fitment issues

I don't like the binary switches.
A 1996 and later R134a HPCO switch is what you want. Ask the outfit that sold you the hoses what the threads are... or measure them.
The stock 1984 LPCO shouldn't be a problem for R12 & R134a as long as you aren't going to run some exotic refrigerant like hydrocarbon blends that have very low liquid and vapor side pressures.
You don't really need a HPCO for R12... R134a has higher liquid pressures.
