Bed support questions 62 longbox

[suburban99]

Ok guys getting ready to reinstall the box.
Truck was apart when I bought it but I think I have figured out where most of it goes...the 5 thicker supports look correct and I think the skinny one goes across the front of the wheel wells? Should there be 2 skinny's? Also have 3 unknown pieces pieces in the picture. Any help appreciated thanks.

that looks right, just 1 skinny.
rust colored pieces might have been supports for that long style step bumper that wraps around to the wheel well.
