I prefer to use old A/C compressor mounts modded to fit the alternator on the other lower side. Better clearance of exhaust and easier access from bottom. Have a home made idler set up I put on that side to aid belt routing due to lack of power steering pump.
I thought that's what you were doing now, but I couldn't remember.
Assuming however that one wants to keep the A/C compressor, and not hack up the hinge like a Thanksgiving turkey, what then? Can the alternator be relocated to the no longer needed power steering pump's location and leave it at that?
