Default Correct Alternator part number

I have tried searching, can't seem to find it. Can anyone tell me the correct part number for a 79 W72 Alternator?

Did some research a couple years back and the number I found for a 1979 W72 is a 63a unit, part number 1105360. Will have to go back and check source…

So, my 1978 W72 alternator is 1102486-61A. Guess the 63A is for more accessories?? Mine just has air conditioner, no power windows or rear defrost.
