Can you mount electric wipers without having an original angle bracket and outer spacer?
Yes, but it will take more than using shims with a clamp nut on the motor shaft. The torque of the wiper back and forth will loosen the nut. Tightening it will eventually strip the threads requiring the motor to be replaced. It could be very dangerous for the mounting to fail during a heavy rain. A better option would be to reproduce the angled bracket or even carve an adapter that had the same angle for aligning the motor with the cab skin. This adapter would need a close fitting lip that went back under the wiper motor at least 1/8th inch to stop the motor from twisting – torque, remember. The outer spacer would have to match the mounting angle and have a provision for the torque control screw to go through and into the adapter on the inside. The original outer spacers were stamped stainless steel. The replacements could be carved from solid stock. When I say, “carved”, I include whittling them from wood, or solid nylon, as well as sawing, filing, and machining them from brass, steel
