az4x4runner

I've seen some 4Runners with a door moulding in that groove in the sides of the doors. I was wondering where I might find those, because I'm tired of people hitting my door with the edge of theirs (and denting the door) when they park to close to me.

I guess I should give the dealer a call tomorrow and ask them, but I was just wondering if any of you had any other ideas since it'd probably be much more expensive from the dealer.

Example (one a car though):
moulding

Thanks,
Bryan
