I found an official GM photo that shows that Delcotron alternators originally had stickers on them. Maybe the sticker fell off soon after the car left the lot, so not many people remember them as originally being there. Even virgin survivor cars may have had them fall off over the years.
Anyway, attached is a photo of a reproduction Delcotron sticker and a photo of Figure 2c (black and white GM photo) on Page 6Y-8 of an original (not reprinted) "1968 Chevrolet, Chevelle, Camaro, Chevy II and Corvette Chassis Overhaul Manual" (dated 1967) showing that same sticker affixed to the top of the alternator, with the Delcotron text bottom pointing toward the pulley.
With the official GM documentation presented here, will the Legends Judges accept having this Delcotron sticker on an alternator at the 2012 Camaro Nationals?
