Another ?? Steering coupler

[kcfirstbuild]

I have a 68 c10 with ram assisted power steering. From what i understand it still uses the manual steering gear box. I ordered a new steering coupler rag joint assembly. I can't get it to go on like the old one.

I have heard that power steering and manual steering have two different sized rag joints. So I ordered the manual steering rag joint assembly, do to that fact I think i have a manual steering gear box.


I look a close look at the new one and I noticed that there is a section that is not splined. So i dont know if I ordered the wrong one or if this one is defective.
