That's a good deal @ 2500.00. I had a 97 ext cab diesel, it ran/rode well. For some reason the overloads both rotated the same direction after a lot of hard work. Consider heavier/stronger shocks for the front if it's a big block. The front hubs are a pain to convert to manual if there are only three retaining screws for the hub. You have to get a conversion kit to the more popular six screw setup. Just a thought, it looks like there is not a receiver hitch, see if there used to be one and check the wiring.
Other opinions may vary 
I know you arent from the "rust belt" but I'd still check to see what kind of shape they are in. The Ford dealership told us that they sell about 3-5 of these new shackle "kits" PER DAY!
