Well I took the 5 screws out of the top fascia on my 21FBS. but was unable to remove it. I don't want to pull to hard but it doesn't seem to move . Then I called the dealer and they told me I had to buy this adapter my self. I told them I don't think so. So hes checking to find a part number. But just how hard do I need to pull to take this piece off the slide so I can get to the motor. Once again thanks for your time and trouble. Marty
