Usually pretty easy to replace generator with alt., just make new mount tabs on existing bracket that bolts to the block to line up belts. If you have broken existing brackets, there might be something else not correctly lined up or welded properly.

Agree with Ed. You don't need to buy anything. You can make, modify or repair-weld the brackets you have. Not sure what is broken, what room there is. No pictures! But just find a few places to attach brackets, spacers and a bar with a slot in it. Play around with it, you will eventually see a way. Post GOOD pics if you want more help. Start by placing alternator in the place you want it in. Prop it in there, use wooden blocks, clamps or wire, then start visualizing how to mount. Does it matter what side it's on?
Post this in Big Bolts, you may get more responses.
