Chip is correct Reisentz Restorations, Sunbeam Specialties and CAT have an
Alternator bracket. The only alternative is to design your own and
fabricate one. I used plywood, it took about 3 iteration to position the
alternator to my satisfaction. I then fabricate the bracket out of steel
and welded it together.
The problem is when you are not using Stock style parts; the
position of everything must be checked. Different parts can have slightly
different offsets or the mounting posts are in a slightly different
position. These tolerances can add up against you or they can work in your
favor. The point is to check them.
I like to use the laser pointer on my infrared thermometer. I line
it up in the bottom of the generator or alternator pulley groove then rotate
it carefully to point at the water pump groove or the crank pulley. A laser
with a pulley groove profile mount would be even better.

Tried to send this from my phone, but for some reason, it seems to be hung
up.
I used the alternator bracket CAT sells. Lines up perfect.
The alternator bracket for a Mark II should work as well. Obviously, they
are a bit hard to come by, and pricey when they are available. You can
purchase an awesome reproduction one from Reisentz Restorations for $160.
