I’ve been focused on steering integrity lately. My suspension guy replaced some worn parts in my 66 Starfire as part of a tire project. I recently redid a couple of tilt & tele columns to make them as good as possible.

Do any of you the size & spline count of the correct rag joint for ‘66 big cars? I’m guessing 13/16’-36 spline, but I don’t know.

Anyone have something authoritative so I don’t get some spare parts that are off by a micron?

Thanks in advance!
