Aftermarket Air 69 Dart 340-6pak

your adjustor on you compressor is on the rear mount , furthest from the belt, is that right?
If so i would rather see it on the front ear closest to the belt . it only takes some flex in the pump and mounts for things to go wrong . Now you are sure the belt is exactly aligned ? its hard to tell from the pics but from one angle it looks as though the pump may be a fraction too far out still , but like i said its hard to tell
