77 Delta 88 A/C compressor questions
Not where this fits, so thought I would start here. I have a need to replace the A/C compressor on my 1977 Delta 88 (with 403 engine). HOwever, I can not determine which unit I have, and neither can any tech guy so far. There seem to be 4 types in the aftermarket. One is a superheat version, a high pressure version, a A4 compressor version, and a C6 compressor version. Is there any way to get this correct? This is the long style compressor. The tag on it does not give much info, other than the type, Delco Air, the Code No. 031473, and the model number 1131122. This is (was) a R12 type that was converted over to R134a. Any clues would be helpful. Thanks in advance! - Al

Is this on your Pace Car?
If your stock A6 compressor needs to be replaced (and especially if its been converted to 134a) you should replace it with a Sanden A6 look-a-like, like this (for example):

Looking at your picture, re: your A/C performance: the long heater hose from the heater core to the water pump isn't supposed to be wrapped around the A/C dryer like that. As it is now you have 195 degree coolant hoses in direct contact with the 33 degree low pressure line - I'd be concerned about the thermal transfer screwing with the low pressure switch's operating parameters.
Easy enough to fix - drain some coolant, then disconnect the too-long hose from the heater core, cut it to length, and re-attach to heater core.
