West Ridge Engine 19

Hello all, I am posting on here as a recommendation from Watt's Truck Center in New Alexandria, Pennsylvania. I am looking for parts for a 1951 Mack L-85 fire engine. The engine is a parade piece and when it was in storage a few years ago, it was vandalized. The engine sustained damage to the door windows and mirrors from a paint ball gun. The vandals also broke the windshield wipers. We are attempting to fix it up for this year's 80th anniversary open house, and subsequent 4th of July parade. I am requesting help in finding parts for the engine. Anyone out there know of a dealer that might carry windows, mirrors and wiper assemblies? They don't have to be new. Just in good shape. Thanks
