Replacing it is easy, but if you have to change camber or caster once its done, break out the BFH and a spot weld driller / chisel.
You have to "Unweld" the upper strut mount from the body, and move it manually. :D
Ford even put studs with nuts so you could refasten once the welds are broke, but still, should have just left the plant unwelded. Took me a couple, and the discovery of a sharp spot weld drill it to get good at it.
