My '64 has factory AC and PS, and is the "late" setup with the single belt for WP/Crank/PS/Alt. I spent years gathering all of the correct brackets and pulleys so I know I'm good there. The alignment seems good to me.

The issue is a squealing belt I just can't seem to cure. I removed the oem-style dated belt thinking that might be the issue, no help. I've tried several different alternator pulleys trying to get more belt wrap without success. Even an extra-deep COPO Camaro alternator pulley did nothing (but drain my wallet). Part of the problem seems to be that the alternator strap adjustment really does nothing to tighten the belt - it just moves the alternator along the same plane, and doesn't increase the belt's contact with the alternator pulley. I've got the adjustment at the PS pump as tight as I'm comfortable with, and again, that doesn't improve belt contact at the alternator. If anything it makes it slightly worse the tighter the belt is adjusted.

I'm about out of ideas and contemplating going back to the dual-pulley setup that was on the car when I bought it, which would be a shame since it would be incorrect for a June built '64. Before I try that I was just curious if anyone had confronted this issue before. I'll get pics up later today if that would help. Thanks for the assistance!
