welcome to the garage Grape, if you look around a bit you'll find a number of discussions about your query .... there is no such thing as a "deluxe" 59, there were various trim options, including a 'deluxe cab option' that was a big back window with the outside window surround and a few interior options, including the chrome .... the various external chrome bits were individual options available on any truck .... no schematic, but you could likely find a partial list of the options in various books, particularly a GM salesmans option booklet - don't recall if anyone here has that - some are also in the 55-59 assembly manual, listed as RPO's [regular production options] that could be installed at the factory
yes, the 59-only fleetside trim is unobtainium [long or short], no one repros the long strips, I've never heard of any NOS, but used sometimes [rarely] show up in the swapforum here or e-bay
