Dorman - HELP Door Mirror Glass P/N:56306
Replace a cracked or broken side-view lens without buying a whole new mirror. The Dorman HELP Door Mirror Glass 57638 is a driver-side (left) replacement for the 2012-2017 Ford Expedition and 2012-2014 Lincoln Navigator. It is designed to match the original mirror glass on these vehicles, so you replace only the damaged piece and keep the rest of the mirror in service.
