Wiper motor was from Classic. I got the less expensive, no frills 12 volt one. No delay and no washer. I don't think there is any thing wrong with the motor, bracket or crank arm. My thinking is headed towards a sloppy, loose original part. Or some geometry thing that is messing up what should be a straight forward system. But, it is hard to get my head and eyes under the dash to see what is happening and it is too cold to pull the seat and hang upside down for now. If and when I figure it out you will know. I was hopeful that some one had figured it out for me...:) Lots of things to try and it will get warmer soon.
