Wondering if anyone can direct me to a place that I can buy a replacement roof trim/molding?

I don't know what it is exactly called but the roof has two trims/channel covers on each side. I need a white one - drivers side.

 

Junk yard or chevy dealer


MOLDING. Roof Panel

 

Just get Grand Prix Roof Rails. Probably going to cost the same as new Monte Carlo moldings from a dealer, but roof rails will look better (more modern).
