Disc brake rattle

I have a 71 Dart Swinger that I converted from drum to disc. I pulled the manual disc set up from a 74 Dart Sport. The conversation is done and works fine but. I have a rattle from the passenger side disc brake pad. It started out as an occasional rattle but as the pad wears it’s getting worse. I’ve taken it apart and checked for wear and loose parts. Everything seems tight and as it should. Is there an anti rattle clip or something that should be there? Does anyone have a picture from a 74 FSM they would be willing to post? I don’t know if I am missing something.
