Tom;
I would agree with you that Don eventually pushed the deuce to be certified for drag racing, hence the correspondence with the NAAR and the NHRA. But, I would propose that his initial purpose, and therefore the design of both the car and stripe package, was to produce an entry for SCCA racing - similar to AAR Cudas. I believe that nothing would have made Don happier than to have his name on the side of an GM built SCCA sanctioned racecar, just like the Shelbys, Boss 2's, and AAR's. When he realized that it probably wasn't going to happen, and the buyers were from the drag racing market, he may have switched gears and requested NHRA cert's.
Sam,
I'm just throwing a theory out there based on lots of small indications like the ones that the Barr bros. typed. That's not to say that the kids didn't make a mistake or two, that already well documented, but I don't know that Yenko would have used a 'stripe mistake' as a brochure photo! I think that stripe application was one of his initial ideas to copy the Boss '2 look, and may have thought it distasteful or to copious.
Either way, Howies find is very interesting
