Since this seems to be the main thread on this conversion, I will add my data point. Rock auto came through with a Denso 80 amp alternator, pulled the plug off a 1991 Toyota pickup at the junk yard. Then came the fun part. Extended the tensioner bracket 3" hole to hole. Also pulled the double pulley off and cut the front pulley off then ground it smooth. This allows the pulley to clear the radiator fan with out trimming. The extension on the bracket makes it so you don't have to trim the fins of the alternator fan. Then the search was on for a longer alternator fan belt. After four try's we finally hit the jackpot.
