Got my Papa's old '65 Fargo back in the family

Man, what a beautiful truck! I'm very happy for you that you were able to get it back in your family. I would probably drive back and forth in front of the guy's house where you saw it first, blowing the horn and waving.....lol. You may already know how difficult the power steering on Swept Line trucks is to work on, so if you see parts trucks sitting around....grab some spares if you can. I used to have a pristine 70 D200 that had that "push me-pull me" PS on it. It had a half round of slack in it that made driving the truck about like driving a dirt track car.
I looked closer at the power steering, it's a Toyota conversion! Looks like an early 80s Toyota pickup box. I've seen the conversion done on 60s Ford trucks, I guess someone did the same on this. It works fine, I have no reason to pull it out.
