Today I looked at a 3100, basically a bare cab, hood, doors and fenders on a rolling chassis, the guy was asking $2k. I almost puked.
Only redeeming factors is the cab is a 5 window and it looks like someone mounted a ford 9" on the back. He had no idea about the rear diff, he got it an an estate sale. I may go back and offer him $500, maybe I'm sick in the head. If the rear is a ford 9 it may be worth it...
