I saw code N98 on the fender tag of a challenger convertible on eBay. Tag looked good but then I saw this code and, in over 40 years of looking at tags, I had never seen it. Was the tag a fake? But then I read that this some obscure 71-only code indicating an emissions label is present. Wow, I had never seen this. And an R on the VON as well. Car needs a lot of work but interesting.
