You could use a 95/96/97 alternator but those used in the US only go up to 35 Amp. Only from 1976 or so did they get a 55 Amp one. Both have an external voltage regulator. You'd be better off using a 99/900: 55, 65 or 70 Amp and a voltage regulator integrated in the brush holder. If you do not have many electrical accesories on at the same time (AC, heated seat, heated rear window, fog lights, spot lights...) 55 Amp is more than sufficient. Also, the 96 one rotates the other way round as a 99/900, so you also have to swap the cooling fan. One more difference is the double pulley on (some?) 900 alternators (like my 900T). -- MH '72 97 '77 96 '78 95 '79 96 '87 900T8
