Schoir,
Ok, I guess I am confused. I found the foam trays on both sides of the rear. I can see a clear tube running out of the bottom of these trays. The tubes on the bottom of the trays had pieces of rubber in it. I assumed that it was a gasket since the tubes seem to sit just under the tray. It appears to still have small pieces of rubber inside of it that I can not reach, but at this point I not real sure about anything
