Alternator upgrade? FJ75/3F (1 Viewer)

[rat]

Please advise me here?
What 100amp alternator will swap into a 1989 3F (gas) 'cruiser, with the least modification? I'm having endless trouble with the stock 45amp peewee . I had it re-wound, to produce more amps (now it makes 70amps at 3000revs) and put on a smaller diameter pulley - still doesn't put out enough power at idle. And the bearings get cooked by the high temp it runs at. Any advise?
thanks guys
Al

I had this 110 amp alternator thread going a few weeks back.

Toyota's big alts are on their 1H# and 1FZ engimes but are mounted on the opposite side.
I think it would be possible to mount one with some custom brackets.
Here are the pics of other alts
