Re: cam sprocket key
Maybe at a Ford dealership, but I wouldn't hold my breath. Not too sure what would interchange (2.8? 4.0?). Used to have a torn down 2.9L, but I traded all related components for a 5.0L and AOD combo. Think I would start looking on a bunch of Ranger related forums and post a "wanted to buy" ad and see if you can find anyone with a spare. Or do what you can to determine the thread and see if a machine shop would have any good ideas. Looks like it's going to be tricky to find short of pulling one from a junk yard.
