commonly referred to as the "Steering Rag" or least what I have heard it called,
You don't take it apart, so don't worry about the smooth Allen looking things, I imagine that you could pick up a replacement at just about any auto parts store, although they may have to order it,
A rag joint refers to certain flexible joints (flexure bearings) found on automobiles and other machines. They are typically found on steering shafts that connect the steering wheel to the steering gear input shaft, usually at the steering gear end. They provide a small amount of flex for a steering shaft within a few degrees of the same plane as the steering gear input shaft. It also provides some damping of vibration coming from the steering system, providing some isolation for the steering wheel.
Yep thats what it's called a Rag joint, and I thought that was just mechanic lingo,
Oh Wait a minute, looks like these older ones do come all apart,
