No it is not worth the fab. work, the axles on a mustang are 2" longer(27.620 Explorer vs. 29.937 mustang), and the perch mounts are different. Also the explorer does not have quad shocks so you will need to weld the brackets on, not a good swap everything is pretty much different you can use the center section(if you buy 31 spline axles), and gears I think thats about it.
