dude, just have a local shop do a high power rebuild on a stock alt. brodway auto elec in san diego here did mine for 200 and it chuns out 120 amps suppose to be a 100 amp upgrade!
no mods needed!!!
um, your stock alternator didnt put out 20 amps.... so i dont know about 100 amp upgrade
just get the bracket from yotatech and get a $80 alternator for a chevy.... problems solved, and way cheaper than a rewired alt, and readily available, cheap replacements should it be needed....
