Thinking about it.... I have a 1985 Chevy 1/2 ton Custom Deluxe 4x4 sitting in my back yard for the past 14(maybe longer) years! I forgot all about that. Bet my wife hasn't! :laughing:
Anyhow, its got a 350 in it with California emissions and a 700R4 automatic transmission (non-electronic with overdrive). Its got manual locking hubs and a (I think) New Process 205 transfer case. All this was stock. 8' bed. Single bench seat in the cab. Served me well for many, many years. We stopped driving it due to rusted body and 2nd child... we all couldn't fit in it. I'm saving the motor, tranny and transfer case for a project.
Here's some more info as to what was available on the "third gen" 1973-1987 chevy pickups... (stolen from Wikipedia, of course).
