Yea, you have to remove the roll pin and slide the shifter base off. Just use a punch to tap it through and pull the base off, it might be a little snug but it will come off. There willalso be a bearing and spring at the bottom of the base. Aslo you will need to shift the top plate over to left (when facing trans from front to back) to slide it off.
