I didn't tape mine to the base at all. I didn't want it covering up the entire shifting base, and probably come un-taped anyway. After I removed the shifter knob, I removed the rubber part covering the hole (it pops right out), then I bent the two short metal lengths of the new shifter boot a bit inward, stuffed it into the shifter hole, installed the rubber shifter cover again, and finished with a tight zip tie on top. I have no air leaks now. I could see people cutting the metal frame off completely from this new Amazon shifter boot, but I thought it would not matter, and stay in place better with it left on.
