OK, You can shave/ shim the bracket at the base and the alternator mount points until it looks like Godzilla's asshole, and it will work.

Or (better) fab a custom bracket.

Years ago (when times were tough) I cut one in half horizontally, mounted it at the bottom, bolted a dog chain to the top, then bolted the other end of the chain to the firewall and adjusted the pitch of the alternator by tightening/loosening the firewall bolt. It worked for years.

Good Luck,

Jeff
