Technical Tailgate Parts

[cachho]

Hey, I'm looking for replacement parts for the tailgate.

1. I need a new tailagate catch/lock, the tailgate doesn't properly shut anymore because the lock does not lock on one side
2. I need the plastic rings, that the tailgate sits in at the bottom.

Can anyone help me find part numbers? Is there an exploded drawing available?
