[QUOTE="P49Y-CY, post: 16879618, member: 10216"] this has been the subject of much discussion through the years. there have been many threads about it, and the general consesus is that the 135a label on the alternator and which show in internal ford documents was an error - perhaps a carryover from an original plan for a higher-amp alternator for the terminator - but that once production started, they began using the same alternator as other mustangs. guys have studied this in great detail, disassembling, doing tests, etc. it's basically a 6g V-6 alternator, with an 8-rib pulley which puts out 105-110a, and no where close to 135a. so it's perfectly fine for a stock-style replacement, which is what you're doing. i've got the same setup as you on both my cars and so far have over 55k miles on a relatively cheap, generic amazon 105a replacement. (i got 140k out of my original alternator on my convertible.) imo the key to longevity is proper belt tension. and as [USER=35549]@01yellercobra[/USER] pointed out, once you start going with bigger fuel pumps, stereo, etc, you need to look at upgrading your alternator.
