Re: AC Pressure Switch ?

For me currently I am trying to convert my 74 C10 to a different form of clutch control. I converted to R134a years ago and the system worked but after letting the truck sit while redoing the engine the refrigerant leaked out. I refilled the system again but was having issues with the main inline fuse that kept turning the blower motor off and I believe freezing up the evaporator, at that the capillary cycle switch would shut the compressor down. So I am trying to use a low pressure switch from a later truck or GM car to control the compressor but I am concerned that the R12 might not have the adjustment range needed.

Re: AC Pressure Switch ?
I ended up finding a low pressure cycle switch from a 1985 that is made for R134a. The Murray number is 36674.
