Some clever racers will do stuff to distract attention, been there & done that, and it is indeed amusing.
But if the BSer & keyboard expert labels are directed at me, I frankly take offense at that.
I'm generally cynical about "new information" and what I call "technical fiction".
Driveshaft ID stripes are well-documented on many other brands, and I saw a post sometime back with a survivor Mopar driveshaft that showed traces of them.
That was something I hadn't recalled from back in the day, which is why I said "look for them".
