Most often these do not wear out but instead get lost. These plastic bushings keep the threaded studs from the window elevators from touching the glass as they pass through the holes in your 1970 bolt in door glass. Eight required per car.
Replaces Ford part # C9ZZ-6323266 or C9ZZ-6523258-B.
*NOTE* These bushings also fit the door glass for the 1969 Mustang Fastback.
