I have a new, never mounted Builtright Industries Bulkhead Accessory Rail for sale. Fits 2015+ F150 and Raptors.
I used the T Slot Nuts from this so you will have to source your own. They are cheap and they don’t include enough anyway. These are used to mount stuff to the rail, all hardware to mount the rail to the truck is included. Asking $275 shipped to the lower 48. Here’s a picture of what can be mounted with the rail.
