This is on my '88 K5. Some of the older steering boxes won't work with this swap due to having a bigger splined end on the steering box. I don't know the years or models off hand, but I'm sure someone on here does.
quote from the tech article.
does the non spline part fit over your splined part?
I haven't tried yet...let me go open it up a little and see...you do mean the steering wheel end don't you?

bust out the welder....
Dieselwarrior did an XJ shaft swap on his K5 by combining the two shafts. It did require some welding, but he got it done. I don't think you have a welder though?

Does one end of the XJ shaft at least fit your steering box? The reason I ask is there are two different spline diameters on the steering box. I don't know what the year cutoff was for the splined steering column but you could always swap out the complete steering column for the proper (double D shaft) style as long as the steering box side fits the XJ shaft.
Also, even having the double D steering column it IS NOT a direct plug and play, there is a small amount of grinding required for the pinch bolt to fit.

Im gonna be doing it on my 73 here in a few days. Going to junkyard on tuesday to get shaft. Depending on what it takes to get it to work you coukd send me yours and I could mod it the same. Just cost you shipping. Not sure if you need it asap or not
Thinking i just need to cut and adapt the stock splines on the xj and weld it up.
Wow. Sounds like a womans problem here.No welder...I am back on the rag for now....
