I have a 94 S10 in back yard. I will be tearing that down soon because my interior is Beautiful. Engine is Great. I am going to put most of the Bells and Whistles in my 85 that is WIP. Wire Harness, Electric Seats, Steering Wheel, Everything except Transfer Case - Tranny. Including the Dash. It's gonna look sharp.
Good luck with UR build, I will check it out as you progress.
