Last I knew you could get the tail gate with or with out FORD on it and the front panel.
Think LMC had them but you can try DC also.
As for the bed sides no one makes them and any you find most likely will need repair of the lip that bolts to the floor. It is not hard to repair that lip as I had to do it on mine.
I made a patterns from what was left of the lips onto cardboard with holes and all.
I then took the pattern to flat stock and made the needed lips.
Holes were marked and drilled in the flat stock.
To make them square for the bolts I took a jig saw to square the holes test fitting the bolts.
Once the lips were made with the square holes I welded them to the bed sides where they went.
I also had to build up weld in other areas and drill and make square holes
I used a long bed style side ribbed floor cut shorter and the sides off and bolted the flare sides on
I took some of the cut up style side bed to fix the bottom of the front panel that was rusted.
Hope that helps
