Thanks for the info, helps a lot. I have the read out of the IBM card from FCA and ‘ship’ date is Jan 25-66. Special order, two options (other than the Hemi and 4 speed) radio and tinted windows. The reason I’m asking these questions is I’m almost sure they where added to an already built car. Antenna was a hack job on the fender in the wrong place and the hole-grommet was nothing more the a punched hole (long punch) in the hinge post. Both front and rear glass was glued in with the black sealer (had to cut the seal to get out). These options are on the card but from the hack job on both maybe it was done after the build not coming down the line. Ever heard of this happening.
Another tidbit, the car, a Belvedere II, has Belvedere I plain taillights not the ones with the chrome bars
