what this hole for? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I took the rear bumper off my '65 suburban to paint it and install a bumper to body seal i am making.
I found these holes on both sides, plugged with a gray/silver plastic plug, the same as those that plug the holes in the side support where hinges would be if my sub with end gates was a barn door style.
I have owned this truck since 1969, i dont remember drilling these holes, but i also havent seen or heard anything about them either on pickups or suburbans. thats the plug sitting on the ledge above the hole.
so i assume they are factory, does anyone know? Name: DSCF4086c.jpg
