Should I Use a Splined or DD Shaft?

What is a split joint?

With DD or spline , all I ever did was add a small notch (machined) for the extra /safety set allen. No need to drill thru the shaft. IMHO ...that would provide a weak point in the shaft.

Maybe I am missing something.

I would suggest incorporating a vibration dampener ...whether you are keeping the stock box or changing to a rack and pinion. Usually on a HDK install,coming off the rack, a combination vibration dampener /universal with a DD end is used.

Re-read post #11. I posted two sites (addresses) showing the split joint u-joints. You don't drill through the shaft (that would not be good). You simply file a slot on the outside of the shaft for the bolt to lock the shaft onto the u-joint. Like I wrote earlier, factory cars came with the split joint and the factory splined shaft had a slot/groove machined all the way around the shaft so you can "clock" the steering shaft wherever you like. The bolt passes through this slot/groove, in our case you only need a slot on the side the bolt passes through and not all the way around so it's actually stronger than factory!! Hole DOES NOT THROUGH THE SHAFT but on the outside.

Factory type example:
