Rare 1967 Mr. Norm's 383 4 speed dart

This Sunday while searching locally for a 69 fender for my Dart, A close Mopar friend of mine took me by his childhood friends (Another Mopar Friend) house to see if he could help..To my surprise, he had about 12 Mopars in his backyard. I noticed a 67 under a car cover and asked about it...Jokingly, he made a face at me and told me not to even look in that direction. As we walked over to the car, he told me the entire history of this rare 67'. It was 1 of 229 ever made BIG BLOCK 383 FOUR SPEED MR. NORMS 'GSS DARTS'. He is 2nd owner and bought it from a local dealership 30 years ago.. Amazing sight to see. He wasn't sure how many were left in the world but I did find one for sale in PA. claiming to be the only one in existance...Anyone know how many still exist? He says he would sell everything he owned (including a AAR Cuda)before he got rid of it..I don't blame him!
