Joe, As I said, I'm only parroting back what Rob Grady told me. Chances are, if you don't know about this service bulletin, then it probably doesn't exist. If this is true, then I was probably told about an instruction sheet which was supplied to dealers with the new locksets. I think Rob referred to a template to show the cutting of new slots in the door sheet metal. So it makes sense that it is really just an instruction sheet. Walt
