Upgrading the alternator

On my pro-rally 510, back a few years, I had a couple of alternator issues.
1. They would fail once in a while from overwork and the belts would slip
with a heavy load on the alternator and hard acceleration.
My ultimate solution was to mount 2 alternators. I looked into how they ran
2 alternators on twin engine aircraft and found out there was nothing
special to do just put them in.
I ended up with 1 60 amp internal regulator and one 50 amp external
regulator ( upgraded to solid state ). The 2 alternators would nicely share
the load proportionally between them with no issues at all. I even had
switches on the dash to turn either off. I was able to underdrive the
pulleys and do away with any belt problems. No megabucks high output
alternators 2 different belts so totally redundant. The second was mounted
on a modified smog pump bracket.
