im no expert.. so hopefully someone could chime in here.

i think the main thing to be concerned about is that it mounts up correctly, and the pulley.

you may have to remove the pulley from your old alt and put on the new one. otherwise im sure you can purchase a new pulley for it too.

for the wiring upgrade i was talking about do a google search for "the big 3"
look for any links that have to do with car audio, from there you should be able to get the idea of what needs to be done.
