I just can't seem to find a setup that has enough grip on the alternator to get it to work. I can if I leave the PS belt off, but that's no long term solution.

Any ideas?
I'm not running AC at this time, so what I did was space the PS pump bracket out 3/4" to use the front pulley so I could use both rear pulleys to drive the alternator.
