So I have a 2012 GSR and the drivers side slider rail is missing the cover like on the passenger side seen as item 16 in this diagram but no diagram for the drivers seat shows the part. Some guy gave me what the number was a month ago but he's not at the dealer any longer and no one seem to be able to figure it out. Here's the diagram item 16 is what I'm talking about.

driver's side doesn't have one. I know it's weird, but it doesn't.
