Alternator question ??????

This may be a stupid question but how do we find out what alternator we have 105 amp or 130 amp

There's a sticker inside your glovebox door that has the option codes (or RPO) codes for your truck. Alternators are a "K" series. I finally figured out that I had the 105 in my truck. Here's the listing, but you'll have to noodle out what's what (and I know - they call them a "generator"!)

K09 : GENERATOR, 120 AUP

K22 : GENERATOR, 94 AMP

K42 : GENERATOR,124 AMP

K60 : GENERATOR, 100 AMP

K61 : GENERATOR, 97 AMP

K64 : GENERATOR, 78 AMP

K65 : GENERATOR, 95 AMP

K68 : GENERATOR,105 AMP

K73 : GENERATOR, 70 AMP

K76 : GENERATOR, 61 AMP

K77 : GENERATOR, 56 AMP

K79 : GENERATOR, 42 AMP

K81 : GENERATOR, 66 AMP

K82 : GENERATOR, 75 AMP

K85 : GENERATOR, 37 AMP

K90 : GENERATOR, 108 AMP

K91 : GENERATOR, 65 AMP

K96 : GENERATOR, 55 AMP, BUILT-IN REGULATOR

K97 : GENERATOR, 80 AMP, BUILT-IN REGULATOR

K99 : GENERATOR, 85 AMP

Thanks Tom apon further inspection in the daylight (guess that helps) It had 105 right on the side of the Alt. itself but I appreciate the info, learn something new everyday.
