No idea, just guessed. Will find out when it gets here!Did you order the larger 24mm bushing?
Any advice on dismantling the console and shifter assembly?

I pulled up around the shift boot trim from inside of it with my hands - the front of that piece that goes to the cubby hooks in and rotates up and out after.
If you have a sport button, you should unclip the harness from it after the 2 screws are removed. Then you can lift the front of the console more and unplug the harness from the dial/buttons controls.
Take it easy the first time, don't want to break any clips.
