I just picked up this '85 GMC Seirra a couple of weeks ago. It is all stock original except for a stock white repaint and the stripes some years ago.
Vinyl Seat, Manual windows & locks, no tilt, no cruise, and not much else. A4.3L V6 with a Q-Jet and a TH400 trans and 2.73 rear gears. The SPID is there, but I don't have a pic of it. Engine is shot at this point, but thats fine with us. We are going to put in a 5.3/4l60e combo. Looks like it had D49 mirrors too, but some PO put on those ugly ones....
Gave it a quick bath with a gray scotch brite and dawn dish soap:
PO had carpet put in and my son and I are in the process of removing it. It was also glued to the door bottoms and the kick panels.
