I just put new black lock cylinders in my doors today to match, I've done away with a lot of the chrome...& Also the passenger side did not work. Driver side was an easy swap but when I took the passenger side apart, I was surprised to find that the 2-3 inch arm that is attached to the backside of the cylinderwas missing. It's gone. Does anyone kno where I can buy this piece? It's kind of a strange request but any help would be appreciated.
