It cost me around $220 for parts from AutoZone (AC Compressor, Accumulator, Orifice Tube, and Refrigerant Oil). I had to have it professionally evacuated and charged by Firestone and that cost me $80. I didn't flush the system because my compressor didn't blow up and throw chunks out. I made a video on how I did it. So far it's working great!
I had problem with overheating on motorway when I drove over 60 mph i changed thermostat,radiator,thermostat housing, nothing helps.Then i find out that the problem was AIR IN THE COOLING SYSTEM try to squeeze all rubber pipes especially where is coming coolant to radiator.
check the temperature of the heater hoses at operating temperature of the engine. are they very warm to the touch. if one is and one isn't, you will require a temp control valve.
an old one ---think it needs a new front clutch and brake band ,but do check for a vacumn pipe from the inlet manifold to the gearbox long shot but it might have a vacumn controlled unit in the gearbox to tell it when to shift doubt it as this was only on cars in the 60s but you never know.
