Regarding the R/T stripe, to my knowledge, that stripe pre-existed before the T/A stripe, so, that's what they used. Also, from what I've read of the history, Sam Posey made the decision that there was too much lime-green color (he, perhaps, actually didn't like the color, but that's what Chrysler corporate wanted), so, he insisted that at the least, the roof had to be colored black to reduce the overall quantity of lime-green.. and so it was!
Now, how about we all pool-up our money and make an offer.. sorta like a real-estate vacation time-share purchase? I can come up with the first digit (5) ... can anyone come up with a few of the extra zeros? I've personally seen this car back in 2010? when is appeared after its full restoration at the Vegas SEMA show... stunning!!!!!!!!!!!!
On my own Challenger that I've used for extensive SCCA Solo II/autocrossing competition, since the year 1976, I've always run either car numbers 76 or 77, predominantly 76.. in a personal tribute to thsoe two carts... those are the ONLY numbers that should be run for these two cars.. in tribute... IMO.
MAN... since this is MY predominat race car number, oh... how I wish I could own it.!!! (and I could've/should've back around 1980).
