Alternator Stamping

Alternator stamping started in mid-69. Before that, it was ink-stamping.

An early Mustang alternator will have a rounded mounting ear (like the picture above) and the word Autolite cast into the back of it plus the inkstamp. The squared off mounting ear is a dead giveaway but the Autolite casting not so noticeable once installed.
