The exterior wiper blade arms are Dyna Radial Arms. I can't get a good position to get up inside the engine compartment to find a manufacture or serial number for the linkage part that moves the exterior arms.
I have a 2008 38' Damon Daybreak Class A Coach with the Ford Chassis. The Windshield Wiper Arm assembly, where it attaches to the wiper motor, has broken. Does anyone know where I can get the replacement part?
