I need to order a replacement trim piece and am having trouble figuring out what this would be called and where to order. This is the trim piece on the driver side, above the rear triangle-shaped glass.

Thanks in advance!!

 

This rear triangle window trim has been discussed here numerous times. The trim piece is held on with a double sided tape and is prone to come loose and blow away. Now for the bad news....Lexus doesn't sell the trim piece separately, instead you have to replace the entire window with trim as one unit. $$$$

Edit: here is a link to a discussion of this trim piece:
