OK, Anybody Know What These Are? Told They're Pontiac...

I bought these in a lot o parts I paid way too much for, just trying to figure out exactly what they go to. A buddy told me they were rear bumper steps from an early 60s Pontiac Safari? I dunno. Just hoping someone can point me in the right direction so I can get them sold and recoup some of my money. Thanks!

No idea how to post pics. The obvious isn't working. Crap. Email me at neil.gobbi@gmail.com.
