Ford specs are very broad but the previously posted specs are within them and work well. Ford twin I beam front ends are not easy to setup. If the shop sets to the posted specs you should be good but you will likely have to purchase and install adjustable upper bushings to get the settings right especially the cross caster and camber. Also make sure your air bags are set so the ride height front to rear is what you will be running when loaded for a trip as it can impact caster settings. Although some shops may say bump steer and heavy feeling steering is typical of Fords if it is set up right the unit will feel, handle, and drive almost like a car.
