Alternator questions

I have a question regarding the alternator setup on my 64 Barracuda. The alternator looks, to me, like a chevy alternator, and only has the one wire comint to it(see attached pics). It also has, what appear to me, to be home made brackets(see pic). I would like to put a Mopar alternator back on this engine, but am not sure what I have to do to convert it back to standard. HELP!!!

Any and all help will be deeply appreciated!!!
