Rag joint splines
Hello...new guy here. I have a 1972 F-250 Camper Special, 2WD, 390.
In replacing my power steering gear box, I am also having to replace my rag joint. It looks like on my rag joint, the splines on the part that connects to the gear box I thought looked worn on one side, but I was looking at this picture https://secure435.hostgator.com/~dlv...UZ-3A525-A&s=0 and it looks like that one is "worn" on one side too!
So, I guess my question is, were these splined all the way around, or did they have a section that was not? I'm trying to figure out if I want to rebuild the one I have or get one of those borgeson vibration dampening u-joints. If they were not splined all the way around, mine looks to be in ok shape and rebuildable.
Any help is appreciated.

I cannot remember if the collar was splined all the way around. The shaft is, and the collar can slide on at any degree of rotation, best I recall.
The bolt tightens the collar around the shaft, so a little wear on the splines, or a blank spot, shouldn't be much of an issue, as long as the bolt is properly tightened down.

Ok, yesterday I was working on my 74, and there is an old rag joint laying in the bed. The splines did not go completely around the inner portion of the clamp. I suppose the blank spot is there to allow the clamp to compress around the shaft easier.
When I had the steering gear off, I remember it did not have any king of blank spot, or flat area on the splined shaft (AKA "Blind" spline). The rag joint could be slid on at any degree of rotation.
Granted, this truck is a little newer, but I suspect Ford didn't change the design much between 67 and 79. They are famous for not "fixing" stuff that isn't broken.......
