can an alternator from a gen 1 work on a gen 2?
 

I have a gen 1 alternator laying around and my gen 2 alt is going fast. I just spent all of my extra cash on my car.
does anyone know where I could get a rebuild kit dirt cheap for the alt?
I would like to upgrade to a series 55 alt as it has higher output. but I will stick with the series 4 if the S5 rebuild kit won't work on the S4 alt.

somebody must no the answer to this.
It is hard to eye ball with both of them still in the car

not sure.. i know a 3rd gen alt fits on a 2g, with slight modification.. It's like, 100 amps too.. Actually, I hear they're "rated" at 100 amps, but many people have tested them and they produce a good bit more.. Of course, that'll be a pretty penny, i'd imagine.

yes it should work, just make sure you get the bigger one
