Fuse panel?
 

in the midst of doing stuff to the truck, traveling a lot last weekend, and packing loads of stuff in my cab, I seemed to have lost my passenger side fuse- cover.
Assuming I still can't find it by the end of the weekend, where can i go to get a new one? Ford dealer?

Ford dealer or junkyard. I can't see that being made as an aftermarket part.
