The rears came with it. They're the 1 piece 19.5s. The fronts are off of a '84 3/4 ton Suburban. I have to use spacers, 2 washers per lug, so that the drums don't rub on the tie rods, but they work great otherwise. I also had to modify them to get the hubcaps to fit, that was a pain.
Good luck with yours!
