I remember seeing them in the JC whitney cat. I was going to use that set up but, never got a chance to sold the big ole girl and went to a 2wd short bed. Your exactly right at what it does as well as replaces. Question does it have a one size fits all cable? If it does I might want to make something a little more custom. Like maybe use a vinyl covered cable considering Minny gets mighty cold during the winter.
It appears they use a vinyl or similar coating on the cable although the pics are kinda small..... What does a South Carolinian know about Minniesnowta winters anyway?? You're right though, it does get downright chilly for a couple of months and those are the times I'd need the 4WD to push snow around with the truck.
