Original Alternator question

What would have been the original amperage alternator for a 72 Blazer with a 350 and A/C


I have a 37A on the motor right now thats not the original unit, I would expect it should be a bigger unit on trucks with A/C, anyone know for sure? I would like to put it back to what it should be but I don't know if it should be a 42 or 61 amp.

Re: Original Alternator question

It looks like a 61 amp was included with a truck when A/C was added to it.
