After removing my drivers side door panel a few times for different installs, the plastic clip that the door bumper (near the rear of the door) screws into has rounded off. I can still get the screw out by wedging a putty knife in there to hold the base but I figure I'll replace that piece since I need to pull the panel one more time.

I stopped at the dealership to see about ordering the part and they gave me Part No. 72144-sz3-013 (part #16 in the diagram). Is this the correct part? Just want to make sure before I order. Not to mention, they want $12 for this when you can get it for ~$4 online.

Thanks
