64 dart 270 rag top Production numbers

Carl: Hey, it's Adam from California - you know, the newbie who can't win one of your ebay auctions! At one point, I found a site that said my 64 273 GT vert was one of only 2,040 made, but for the life of me, I can't find the source again. I will keep looking, and I'll let you know if I come up with anything. If you find any info, please do the same.
Thanks & Good Luck.
