It just so happens I'm in the middle of an A/C job right now and came up with a list of what I've spent money on.
This is basically for a full rebuild minus the evaporator and condensor. This list assumes you are replacing the compressor and are keeping R12 in the system.
The receiver/drier I got here from pelican was NOT ruined when i got it but I ruined it myself by exposing it to atmosphere when i opened the caps
