I moved my Moroso drive to the driver side, and used the stock long water pump bracket for the alternator, but hung it under instead of over, fabricated the adjustment arm from the upper mount with an axe and saw, use a Moroso 50% drive pulley for long water pump applications, and it all works fine.....can't run the fan on the alternator because of the adjustment arm, but you could do a better arm or just take the fan off the alternator.
I thought you have seen the pics.....
Copy and paste, I can't make it a link or image........
