Can anyone decipher the correct part number in need for the black strip on the side of the door near window. My drivers side front piece has cracked and is now chipping away. I want to order this part but im having a hard time telling what part number is the correct one.

Here is a diagram from Sewell:

 

I think this is what you are referring too.

Edit. I was wrong. Let me look again.

OK Maybe 75756C for drivers side. It's very confusing. I think a call to the a Lexus dealer is in order.

Fixed the link again. Funny you are talking about this part. I was thinking about getting one myself as mine has a slight dent and is loosing the black paint on the edge.
