I have a 1993 Chevrolet K1500 with a 5.7 that I am changing out the alternator on. I am updating from the standard 105 amp to a 125 amp, but the larger 125amp alternator body will not fit into bracket that the 105 amp was in. Is there an after market bracket, or a bracket from another Chevrolet make and model that I can use?

There is a different OEM bracket. You would need to visit a junkyard and find it. Or Google GM 125 amp 350 bracket.

Mike, I have Googled this all kind of ways and cannot located anything. I have surfed the web, looked through youtube and nothing. I don't know if it is the way I am looking or what. Do you know what vehicles these brackets may have been on?

Even I had a hard time finding info. It'* the 140 amp alternator that comes stock with some 5.7 platforms, not the 125 amp. My bad.
I still can't find a reference for the OEM mounting bracket though.
