at the front & rear the floor lays on a horizontal sill, spot welded.
the sides have about 1 inch turned down that mates to the inner fender. again spot welded but mine were rusted
beyond recognition.
only 1 cross brace extends beyond the bed floor, it widens out and is welded to the inner fender.
basically the floor can be separated by drilling a bunch of spot welds.
the front & rear while it's right side up. the side seams are easier when removed and up-side-down.
I removed the fenders last year, but they could stay attached when you remove the floor.
all the fenders, front wall, and rear sill can remain intact when the bed floor is removed.
does this answer your questions?
I have another bed on a stand if you need detailed pictures.
