Concerning the brackets on Ebay,
I have seen several factory and hotrod applications where the belt wrap on the alternator was less than 90 degrees and they worked fine.
As the add states, the brackets have plenty of front to back adjustment to account for different belting arrangements.
In other words, it works with multiple belts as well. The pictures currently show this. If you have any other questions, feel free to email me.
Thanks,
Bryan
