Help! I need a part!
 

I am trying to figure out the part name and number for the black plastic trim piece located between the driver side door window and the very small rear/side window. I broke the little ball/slide in piece off of the top of this piece and the top of it flaps while driving. Where is the most reasonable priced place to order one from and I should be able to do this myself right? Thanks for your help!

Check Courtesy Parts. They have 'sploded diagrams to help find what you need.

:tup:

are you taking about the b-pillar cover mounting tabs? i'd just use some 3M mounting tape (vhb)
