Alternator line up

I would suggest that you quit trying to eyeball stuff with a nail. get a real straight edge (an 18 or 24 inch level) and lay it flat on the face of the alternator pulley (not the thing that sticks out of the face of the pulley) and see how far off you are from the other pulleys. Measure it. Then you will know if you can move to the other side of the outer alternator bracket, or how far you need to shim all the alternator brackets to reach your goal. I just had to do a lot of this to align a poorly designed pulley system for a small block with aftermarket AC, water pump, 2 groove alternator and power steering. You can do this if you know how far from aligned you are.
