This thread is about a year old but I have a question that pertains to it. The final nut on the outside of the wiper arm, is it reverse threaded or conventional? I'm trying to swap out the motor since the arm connection is stripped but I can't get that final (big) nut off. I sure don't want to tighten it more by cranking on it the wrong way. It doesn't make sense to be reverse threaded but maybe it is. Does anyone know? TIA
