Newer serpentine system and a.c. compressor

Thanks, my sons a.c. compressor has never worked and weighs a ton. He wants to get a new style one and I thought a complete system from the pull apart yard might work.
From the Magnum, you’ll need everything from the timing cover forward and an electric fuel pump. I used Edelbrock carb fuel pump. If this is in an A body car, you’ll need a van PS pump bracket if you have PS. Or relocate the battery. Use the proper refrigerant.
