Yes, definitely NMW. They don't seem to be as popular as Camaro tabs but I'm sure someone would dig them. Heck, I buy these just to collect / build a library. I have some for a 69, but not the 67/8. I make copies for some of the popular ones, but nobody has asked me for these in the last 10 years. I don't think that takes away for the coolness at all.
From a collectibility, 1st design is cooler. Functionality, the 2nd designs are likely better/ safer.
