Barry, simply remove the fuse that controls the seat belt extenders and forget about them. I've done exactly that on our three 300CE's. It's far simpler to reach back with your hand just above the floor and grab the seatbelt than fool around with the presenters ... especially for passengers unfamiliar with the presenters. On our 1992 300CE the pod trim piece came loose and interfered with smooth operation of the presenter ... solved that problem too.
