Tilt column, split bench seat, power bench seat, etc. are all up scale options that are fairly rare on a Chevy (entry level to GM's fleet of cars). On a Cadillac, or a Buick they are standard equipment, on an Olds or a Pontiac they are much more common. All interchange with each other.
Keep[ in mind that all brand names used the same B-body that they bought from Fisher, only difference is the grill, the trim and the Motor before 1974. After 1974 most used a Chevy small block for a V8 and a Buick V6 if a 6 as the brand specific motors were no longer produced.
