Help needed in replacing shifter plate

[scameronh]

The plastic plate that is around the shifter arm on my Eurovan is broken. This is the plate that moves when you move the shifter. It helps to seal the cabin. Mine cracked and broke so now I can see through to the underside of the car.

Couple questions:
What is this plate called?
Where can I buy one?
How do I replace it?

Thanks for the help.

Thanks for the input. I ended up using the plastic sheeting from the bottom one of my wife's reusable grocery bags. Looks perfect and easy to cut.
