Your trim package is custom. Includes all that chrome, grill, and some interior bits. We need more pictures to see it all. Might find an RPO designation on the tag up by left cowl or on a build sheet stitched into frame of seat. You can read all about the features from the heritage pages (links within stovebolt).
The fleet side bed trim is hard to find complete and if you have trim under the rear window that's hens teeth. I would not separate or piece the trim out. And I would treat it with care.
Not sure of condition of cab and panels but I would think the truck should very much stay together. I suspect we can find a bit more info on your truck if you review the left cowl tag and find the build sheet
