Converting to 12 volt

[jeepnbrat]

I have the basic idea on how to do the conversion, but where can I find a pulley that fits the stock belt?

I just used the pulley off of the generator it fit the shaft of the alternator perfect, BUT I also know that they used different generators throughout the years so you may have a different type. You need to find the type that seperates from the fan behind it.
