If by the spline, you are talking about the actual shaft that goes into the power steering pump, that is fine. I had to pull the steering column and the power steering pump when I was tearing the car down. (I now have the straight subframe on, with discs in the front and Hotchkiss springs. It is actually back on the ground now on tires!!!) So, I have to put the steering back in so that I can steer this thing when it is time to tow the car. The coupler itself is okay, but the rag joint was torn and tattered when I pulled the column. Even if I got a different kit, how do those pins come out so that a new one can be put in? Mine actually look pressed in and almost look welded from the underside. Kind of like the original ball joint I had to drill and chisel out of the upper control arm. NOT FUN!!!
