Before doing that, what is the possibility of getting a longer bolt, same thread/pitch and using a spacer to enable you in installing it to one of the existing bolts? It may be that cutting off a portion of the clamp is possible, too. Clearly, to me, the difference in the way the alternator assembles is the reason the clamp does not work as intended in the original configuration. A little modification of what you have (the clamp) is better (to me) than re-configuring the alternator. If you do that, and you have to replace that alternator, you'll have it to do again. Just modify the clamp and make it work with what you have and you'll be good to go with replacement units.
