Can anyone identify this?

I got this 1930 Model A Truck as a basket case at an estate auction. I'm working on putting in together and I'm running into some mysterious pieces.
I have these 2 pieces of wood that seem to be part of the assembly of this truck, but I can't figure out where they go. These pictures are of just one of them, they are identical. I invested in the book by Les Andrews, volume 1, but it doesn't go into the wood parts with much detail. Does anyone recognize these pieces?

Those are the bed sills. https://www.snydersantiqueauto.com/product.htm?pid=984447&cat=41818

Thanks. I should be able to figure it out from here.

And I'm pretty sure that the wood is ash.

Possibly maple by the grain pattern, but maple usually yellows out with exposure to air. That's pretty white.

It is indeed the wooden rails that mount the bed to the frame. Probably oak or ash but who cares, use it!
