Dorman - HELP Windshield Wiper Arm P/N:42590
Hold your front wiper blade against the windshield with the Dorman - HELP Windshield Wiper Arm, part number 42812, a direct replacement for a worn or damaged original arm. It fits many vehicles, among them the 1980-1993 Ford Mustang, 1983-1986 Ford LTD and 1980-1983 Ford Fairmont. See the "Vehicles it fits" section for the full list of applications.
The wiper arm connects the wiper pivot to the blade and uses spring tension to keep the blade on the glass as it sweeps. When an arm loses tension, bends or works loose on its pivot, the blade may chatter, streak or lift off the windshield.
If a tired or bent arm is the cause of poor wiping on your car, this Dorman wiper arm is designed to install on the existing pivot in its place.
