4 center caps for 70 & and up buick rally's and maybe other models,these have the black center with the tri logo,only 1 prong is missing out of the whole set,2 are a little lighter in color.nice driver set,nice chrome,located in auburn mass.$80 plus the ride in a prepay post office box.i can email pics to the serious buyer,pm me your email.first in line will like them.
Those sound like they may be later 70s caps. Do they have a black decal in the center with a trishield emblem on it or do they have a plastic lens in the center?
