Are there any good Toyota or GM type alternators (say 100 amp or so), that will fit the Mopar bracketry without modification?

I need a bigger alt, but I have the March serpentine pulley/bracket setup. These billet brackets fit the stock mopar alt I have, and I don't wanna have to hack them up. And would the shaft on the toyota/gm alt be the same diameter as the mopar ones? So I can use the same serpentine pulley I have now.



thanks guys
