Fortunately, I was in the woods and not some desert. No shortage of small twigs that fit in the rail. Should've known to have two socket extensions in the glove box for this inevitability.I agree. This is nuts. Fortunately with your seat I believe you may be able to kick it into action by sticking something ~3 inches long into the rail where that piece was. With mine the piece is still intact yet the same malfunction is occurring. I'm pissed.
