i miss readed my bad. i thought it was a bronco but i bought a kit for my 73 f100 long bed. same as the 79. it was a complete kit 6 inch superlift. had the blocks and add a leafs, and new coils and bushing track arm drop pit man arm. and pro comp es 1000 shocks, through 4wheelparts center. and i also got super swamper tsl. with shipping for around 1300.00. now you can still get parts there for a lift. for the older trucks but i think the only company that still make kits for them is superlift that is what mine is. they make one up to 9 inches for the trucks. maybe a 12 inch not sure.
