There were 2 bench seat trim levels 68 & 69: base (= Belvedere) and Decor (= Satellite).
Base trim of course had no seat medallions.
Base seat inserts use different grain in 69 center than in 68, but their door trim panels still used the 68 Reed grain in the center area.
The 69 bucket cars used the Decor interior other than of course the seats (= Sport Satellite & GTX).
