Okso I’m in the process of rebuilding various things on my 87 GLHS. Most of thecar is in pieces but I’m at the stage of putting thing s back together. The carcame with A/C new, but when I purchased the car the A/C was disconnected withthe only parts left on the car were the, Discharge and Liquid Line,Expansion Valve, and the Evaporator Core. Not knowing the statusof these parts I have bought replacements for all along with the A/C Condenser, and a newDischargeand Liquid Line from RockAuto. I plan on getting a new Compressorw/ Clutch w/ A590 Compressor; all of the parts have been the Four Season Brand.Here comes the question, the Suction and Liquid Line isn’tavailable on RockAuto for the 87 GLHS but it is for a Shadow of the same yearwill this line work on the GLHS and are the A/CReceiver Drierthesame for the cars. I was told originally that when hooking things back up anddoing the conversion it would just be a matter of add R-134 and oil over theold 12 along with low and high psi ports. Is that correct? Thanks for the help.
