I have used the small Nippon alternator on some other cars and tractors but belt sometimes it's hard to match pulley, shaft size on Nippon alternator is smaller so you have to find a wide pulley. All will work.

Vince is right on...
I will add that most little Nippon alternators (the ones with a V belt pulley), have enough meat to stick it in a lathe and widen the groove to fit the stock model A belt. Great little alternators, I've used several now in cars and tractors, never paid more than around $50 for one, new, on eBay, with free shipping. Carried in most auto parts stores for tons of foreign cars in an emergency, but the bargain is on eBay. Easy to make mounts yourself. Have yet to have one fail. Caveat: No 6v version, and no pos. ground version that I know of.
