Sure looks like a column shift tube and lever to me.
My original '70 Duster column had only the plastic bushing around the shift tube and a foam seal above that. The shaft itself had no lower bearing of any kind. Still doesn't.
(This photo is after I removed the shift lever on the tube - converting to floor shift)
I did the same thing. But am I supposed to remove the tube and put in a bearing? Or just leave it like it is? Which is "correct"?
