Need Small Block with A/C Pics, Wiring Diagram

I bought a 75 Dart sport with 318 and a/c and when I got it, it had the wrong alternator on it (100 amp). I've replaced it with a correct one, but don't know how the spacers go, or how long they are. Or if there are 1 or 2 spacers. I'm assuming the pivot bolt gets a nut on the backside, behind the rear bracket.

Pics and measurements would be awesome.

Also, what color wires go to the field connections? There were two blue ones on the 100 amp, but I thought there should be one blue, one green.

Anybody have a 1975 wiring diagram? (Mine has the emmisions pkg. and a catalytic converter.)

Thanks!
