Jeep cherokee steering joint replacing the rag joint

[Anti-Ricer]

My rag joint is wore out on my 65 Chevy steering shaft and I was looking at replacing it when I came across a thread where a Guy done away with his rag joint and put a 90s Jeep cherokee telescoping UV joint or whatever they have on his truck.He said it's a direct replacement with no modifications at all.It takes some of the slope out of the steering that a rag joint has in it and it gives you more clearance. Now here's the problem he never said what year and I don't know what the part is called.I also can't find anymore information on this or anything.I'm going to need it replaced soon so if I can find out what I mere from the Jeep I'll go ahead and order it. Can someone shed light on this modification and what all I need and what year I need it from thank you.
