Not to sound ignorant but where is the date stamp located? I dont spend a lot of time looking at 50 year old alternators although I apparently now have a dozen of them....I prefer the 130 Amp computer controlled ones that come on the magnum engines.
It on the only flat part of altenator about in the middle.. If you can't find it I will have the body shop send you a picture on one tomorrow.
Thanks,
Roger
