BKH:
At this time, that is the only known deuce that came with the exterior decor package and window moldings, neither of these are specific to an SS though. This car appears to be a factory mixup. It was initially thought that during the course of a 'modified' restoration by a prior owner, these options were added to this car. However, after receiving a photo from the original owner while the car was still Gobi, the options and emblem placement were evident.
A second note, one original owner deuce in NH has a FG, A/T, P/S, car that came with an SS tail panel, only. It is believed that the car was probably damaged on the lot, and it was cheaper to slap on the SS panel than it was to repair it.
