You actually did show the VIN pad in several pics, but none close enough to see a VIN. If you say it's smooth though, it is. One way to tell if it's a very early 833 non OD, is to check and see if a 904 slip yoke will slide into the tailshaft. I think it was 66-67 that used those yokes. The 68 ^ 833's used a 727 sized yoke. Good luck with the sale. :)
