Need some small parts that will allow me to mount my radio in the car. These are the same ,I believe, for AM & AM/FM radios from '68-72. 2- small studs that screw into the lower portion of the chrome faceplate. These studs also protrude thru the dash steel & are secured with hollow nuts. 4- thin steel locknuts that screw onto the threaded tuner & volume shafts. Anyone have these available??
