Does anyone know if vacuum wiper motors were made with different strokes? I’m trying to use a stock vacuum wiper system on my ’41. My problem seems to be that my wiper motor stroke is too long. The truck has a stock height windshield. The wiper blade hits both the windshield center divider and the top of the windshield frame. I have tried the motor that came with the truck and one off of e Bay with similar results. I have also tried various length arms and blades, but the results are always the same the stroke is too long.
