AJE makes a kit for early shock tower Fords that esentially replaces the front suspension and steering with a FOX Mustang design, using struts and coil overs that attatch to the top of the shock tower, but you can trim away most of the lower sections, and the Fox rack and pinion, or optional Pinto rack. Looks pretty slick to me, and I think its gotta be a better system that a Mustang 11setup.
