Marty, I looked for the correctly plated (ZD) in reproductions about a year ago with little result - all were cad plated. Finally found the correctly plated retainers at a Mustang shop in Kentucky. May have been Kentucky Mustang or something like that. Talked to the owner and he was super nice and helpful, knew just exa tly what we were talking about. Fred B. put me on to him and may chime in with the correct name and addy. If not I will try to dig up the ticket. Fred, can you help?
