The term "Mustang II" or Pinto is like the term "Crescent" is to an adjustable wrench. The current offerings share NOTHING with the original Ford offerings. No folded tin cross member, no stamped upper A-frame and lower control arm, no strut rod, absolutely zilch. The present quality kits with moly tubing and spread lower A-frame are many times stronger than most factory full size components. With that said we tend to use front frame clips with the CORRECT track widths as all the engineering, engine mounts, motor mounts, brake and steering system is already in place. The main picadillo with this is designing a core support so all front sheet metal aligns. Other options are the Dakota, Aspen/Volare, and LTD. Have not done those but have seen others. Have done Corvette and Jaguar which worked out well but requires a deep "C" notch in frame horn which is no problem if the truck isn't being used with a push bumper. A trip to a junkyard with a tape measure should yield something that will work.
