Re: Rack and Pinion Steering?
As far as I can tell the difference between the Mustang racks and the Explorer racks is that the mouniting bosses on the explorer rack are closer together and more near the center. The mustang rack's mounting bosses are near the ends of the rack. It also seems that t "V" shaped shaft that goes into the the steering shaft is larger on the explorer racks.
This larger shaft is hard to find a U-joint to fit it. So if you dont have the shaft out of the donor ford you might be out of luck.
