For me, it would be easier to drill holes in the plastic of the center console to cut out a pin. One of these holds the shift lever to the base. Then you remove half of the shift lever and replace the switch.
The holes would be covered by the seats.
For me it would be easyer to drill holes in central console plastic, so you can tap one pin out. One holding gearshift to base. Then you remove half gearshifter out and replace switch.
Holes would be hidden by seats.
