Hello helpful friends. I know I need a 3 speed motor. Based on the pics, what else do I need? Where do I buy bolts to mount the wiper arm mechanism under the cowl? The OEM arms seem a little loose around the joints, will this be a problem, any suggestions to tighten up the joints? I live in the desert so I will never use the wipers, more of a cosmetic task of filling in the holes. Any advice will help. I am buying my motor from a guy named Bruce Somer here in SoCal who seems like a good guy...
