First time I pulled my right front door card, this part was missing. Some ham-fisted fool had replaced the DHC previously and just left the whole thing out (along with a list of other butchery performed while they were in there).
Not having one on hand (and no chance of getting one for weeks) I made a temporary one from soft plastic - I intend to replace it next time the card comes off but so far it's been in there for about 3 years and it still holding fine!
