Alternator upgrade

While driving home yesterday my alternator took a dump. I was wondering if a newer style alternator, denso I think, would fit on my car, its a 360 engine with edelbrock heads. I have the march serpentine belt conversion for my car. I didn't know if the denso's come in serpentine from the parts house. If it did I would just run that pulley instead of transferring my march pulley to it, its kind of a pain to do. i know my pulley looks better but for ease of replacement it would be great to just leave the pulley on from the parts house. I have the march alternator brackets too, I didn't know if that would be a problem fitting or not. Right now I am running a 5 rib serp belt, didn't know if that was what the denso's are or not, i would need to keep the 5 rib belt. Any info would be great, also how it hooks up if wiring is different would be a big help too. Or is it just easier to get another replacement alternator like the one I have and press the pulley that i have on the new alternator. Thanks for your help!
