Smallblock alternator relocation ideas?

I've got an issue with throwing my alternator belt. I have an electric water pump, so my belt only runs from my stock crank pulley, to a powermaster (chrysler case) alternator. Also manual steering so literally the only accessory using the belt and pulley.

I believe the issue is the fact that it's a 140 amp..so i can only imagine the draw it's under at my shift point of 7200 RPM. So i'm asking alot of the belt to stay on at that point.

Anyways, i think the best answer is probably to try to low mount the alternator, and get a shorter belt on it so it can't bounce and walk like i'm sure it does now.

anyone else relocate their alternator? any pictures? does someone else have another idea altogether like switch to a gilmer belt and pulleys? I'd rather not ditch my newish, nice, properly functioning alternator.

appreciate the feedback.
