tangovino,
I'm not up to speed on the battle tanks, but if you find a bracket that might fit, it's pretty simple to use washers (SAE) to stack either in front of or behind the mounting lug on the alternator. This moves it forward or backward the thickness of a washer for alignment purposes. The total stack is tight enough that when the long bolt is tightened the whole assembly is snug.
This same thing is done using nice turned spacers, but the stacked washer deal isn't totally hokum!
