Hi chuckmc8, i'm going through ac install on my 5.3 in my 68c10. I ended up using trailblazer ac compressor because suction/discharge lines are in-line front to back and you won't have to notch the frame. I used the trailblazer ac mounting bracket and will need to weld on 2 mounting pads on the side of the pan edge like the trailblazer pan. Some factory a/c compressors have a pressure switch in the back end that may hit the mounts, not sure though. I'm in the process of editing pics soon as i took pics during engine removal with ac mock-up. Good luck, Brian F.
