E30 Alternator on E21?

[ryanwnixon8]

I have a bum alternator and would like to get a little more amperage than the 55 bosch reman.

I have seen some say that an E30 alternator will fit with the '84-'85 adjusting bracket and some tweaking. Does anyone know if this is true?
(I have a '78 320i and this is my first project car. If you think It'd be too much of a hassle and should just get an e21 alternator then let me know)
