OK the story is the taller ones are the only ones for 69 RR bench seat H2 interior cars according to some Very Respected Resto guys.
I have seen survivor cars with ALL original interiors with both designs.
I have an all original interior 69 satellite and it has the small ones. Early build date.
Most A12 RR's should have the tall skinny ones, or later built cars also.
I am not sure if the assembly plants come into this equation on what medallions are used either.

You will have to decide yourself on which is CORRECT for your car.
pm me if you need more info as I have just gone thru this myself.
