Gary, I used to own a 1994 F250, with the 460. I bought it from my boss, he bought it brand new.
He had the "extra" leaf put in the front, I believe Ford had them for the "sagging" front ends.
My 1986 is stock, and I like it better for two reasons:
1) I'm getting more crippled up and it was harder to climb into and work on. I put some Carr Hoop steps on it also.
2) When I would go across the ruts in the streets that are made in the winter around here, I would have to reach down on the floor and pick up my teeth!
It rode rough.
Just some thoughts.
Might have to go with the Hoop steps on the 86, it came with Carr Giant steps I think they call them, (they are higher) even got supports that weren't installed, and bolts, nuts and washers from Carr at no charge!
