As far as the scoops & etc, a lot can happen to a car in 56 years - lots of those scoops were added.
Hood scoops were not an option, but included on GTXs.
A side photo of the car would be helpful, but:
Satellite trim would be a molding along lower body line with silver paint below that.
Being from the rust belt, I'd bet on rust repairs, Satellite moldings removed, and rocker moldings added.
