I am making experiences and bought this alt for US100 . The only way to fit the original belt was to oblong this hole . The cause is the body dimensions (diameter). It was touching engine bracket and the L bolt could not arrive to the end of the alternator support. So i oblonged this hole only in the alternator center direction and used a big double washer to keep bolt tight- very tight , no movements on alternator . of course offroading all is different . With 10 mm bolt i will need to take bolt out in case of change the belt ( not a big deal ). Thats the reason i loved your idea , a bushing with the oblonged shape should fill the space.....Anyway i am driving it only in the city and for experiences. A question: when the bolt brookes alternator will loose but wont drop , true? Damages?
You could try a bigger pulley too...or even changing the size of you belts. That would get you a little more adjustability with the L-bolt (which I'm assuming is the top bolt in the adjustment attachment). Otherwise, I would go with another alternator. It's really important for all of the alternator bolts to fit as tightly as possible.
How many amps do you need?
If one of the two bolts breaks, the alt will flop around and you'll hear a noise and will likely see your temps climb. There is usually enough time to react and shut down without incurring much damage. Usually.
