does anyone know the alternator rating for the 91 mustang 2.3L?

Hmmm.... Try solving this problem in reverse. Instead of finding the rating for a 1991 2.3L Mustang, clean off the alternator and search for any identifying marks, labels or serial numbers and search directly off of the alternator. I was able to match a factory A.C. Delco stereo to the appropriate car using this method.

You can try getting it bench tested at your local auto parts store ( i.e. AutoZone)or they'll have the specifications on the computer terminal. Write them down while they're up on the screen.
I searched on Google.com and found the rating to be 75 amps and I'm assuming 14.5 Volts ( because pretty much most factory car alternators run at 14.5 Volts ).

that or just call and ask them. it should say on their computer

Mendari's correct! It's rated at 75 amps, and a normal alternator ranges from 13.8-14.5 volts.
