Shifter boot!
you can't know which size your shifter uses until you disassemble your shifter . Some repair kits send all three size metal parts for about $100, so you'll have the right part when you open up your shifter .
Personally I would just remove the plastic piece completely , and not put in the metal piece . However this will let your car shift out of park even when the car is off , or no key is present .
So assuming you don't have children or pets that might knock the shifter out of park accidentally it's ok to remove it . If you need the added safety of the interlock you can get the metal piece
