rear floor heat vent?

rear floor heat vent? Mods please delete

I have a vent for the rear heat on my 99 Tahoe that is missing. Is there anyone out there doing an interior swap or parting out that might have one I can purchase? I dont know a part number or know if it is interchangeable with either side?. I am looking for the one on the floor behind the drivers seat. Here is the interior color from the build sheet I looked up

13D TRIM COMBINATION CLOTH,LT GRAY (13D)

13I INTERIOR TRIM,LT SMOKE GRAY (13I)

Please let me know a price if you have one.

I am in Wheaton IL 60189 for shipping purposes

Thanks
