If you are satisfied with the smoothness of your lever, no need to worry! It would cost more in shipping it back and forth than actually polishing the shaft...
And if it turns out bad... I'll fix it.
For the other, this is the last call! Closing very soon! I don't want the other that have confirmed there order to wait too much.
Why would the shaft need to be polished? To fit the actual shift knob? I also have your shifter and IM going to install it soon. What kind of polishing are you talking about?
