High output alternator recommendations

i ran the 1970 up(squareback) chrysler alt for years . you could buy these from rebuilders with ratings well over the advertised 60 amps. in fact you could rebuild your self using available parts to boost them to nearly 90 amps at one time. went thru 3 or 4 of these in the last ten years. seems like the duty cycle is too high as they wear out quickly. finally got smart and ordered one to fit a 89 mopar v8. rated at 120 amps it is the same Nippendenso that Toyota used with the internal regulator for years except this particular one is designed for the Mopar external electronic regulator and has the v belt pulley. seems to charge more at low rpm. nice part is its available at any parts store .
