I think Adam/Lonny might have to chime in. Based on what they sent me (no heim joint included), I think this is the only way it can go together. The white sleeve can be removed, and the stub looks just like what you posted.
I think this would work, but I feel like it's going to pop off. It just doesn't hold as tightly as an actual metal ball joint like the other side of the shifter uses. And with the heim joint like what you have, there is no way in the world it can pop off because there is a retainer clip.
I'm really confused though. I don't know if I was sent the wrong parts, if this is an SS/TC thing only, DF started changing the way it hooks up, or if this is indeed the correct way.
