I used to race a '78-80 Olds Cutlass and would tear off a bumper every now and then. I thought I pulled these lights from one of the bumpers I replaced, but it's been awhile and I can't remember exactly what I pulled them from. Can anyone identify these, and if there was a version of '78-80 Cutlass that had lights mounted in the bumper? These are for sale, $40 OBO plus shipping.

 

Dug through my files and I did take some pics of the junk yard car I pulled these from. Makes me think this is from another g-body possibly, and not Cutlass, but the bumpers are interchangable?
