As shown, they would have to be thin to fit between mldgs & glass.
Term spacer could just mean a thin type of trim piece (rubber, plastic).
Maybe any early year item, abandoned later on?
I have factory diagram/prints right down to the actual assy line rigs used to hold/install the E body glass along with the procedures to be used on the assy line from 70-71, no such mention of an items, perhaps it's for another model?, sometimes FSM's use generic pics? or group in other models/methods in their text...
