The "XLT Gold" badges could be a dealer added option, based on the region in which the truck was originally shipped. I remember there being an "Oklahoma 89'er" package on some trucks that came into the dealership I worked at back in 84-86 timeframe. The badges came loose inside the truck, and were supposed to be installed by the dealer.
There was a pickup that we got thru a dealer transfer from Texas, and it had some other kind of badge on it, specific to Texas.

Nice find.
