Not a mustang question but it is ford related. How big a job is it to change the slave cylinder in a 91 Explorer 4X4?? Have a chance to get one but it needs a new SC put in it. And seeing as I have 2 spare 5.0L sitting in the garage I figured over the summer I could swap the 4.0L out and drop one of the 5.0L in for a fun winter vehicle
