This a NOS Ford brake pedal to master cylinder rod retaining clip which is correct for all Ford cars made from 1967 through 1973 and later. This clip snaps on to the end of the master cylinder activating rod to hold it into the master cylinder and keep it from falling out. This is a safety item and must be in place to insure safe brake operation. Do not trust your safety and your families' safety to a crappy import repro clip which comes from who knows where. You can trust all original NOS Ford and you can trust this clip to hold fast. This is still sealed in the original Ford package.
