[FC] RE:Greenbrier rear bumper

[B Brewer]

Hi,
I know the downsized 1978-84 Malibu wagons used a rectangular light in the
bumper with a built-in backup light as did the 1978-87 El Camino's. Perhaps
the same vintage Olds Cutlass Cruiser wagon used the same. Don't remember
about Buick or Pontiac. I can't remember about the larger mid 70's wagons but
I think they may have used a different style in the bumper light. Hope that
helps and gives a broader search than just a Malibu wagon.
