Sorry Scott but you are wrong, that does NOT replace the rag joint. There is a rag joint && that odd ball joint up. They used simslar ones on GM cars from the mid 80's back & as we both can tell some of the trucks also. You can't see his rag joint because it's at his steering box. Looks similar to what was on my 68 Chevy truck.
Can you Pull the joint & shaft completely off of the column & steering box && take pictures of the complete shaft w/joints?? PLUS a picture of what it looks like were it attaches at the column. That way we all know what your talking about & what everything looks like.
Kevin, if you have a boneyard that has some mid 80's down GM cars & trucks you should be able to find a used one. Personally I have never seen one fail before, so yours is a 1st for me.

Kevin, Check your PM's....Joe
