I checked the park position on the motor and I am good there.

In searching for P/N 3431514, all I can find are the drive arms with the metal clip-type bushings. I am thinking those ended in '73. The wiper arm set up I have has the polyurethane bushings that I believe started in '74. The drive arm that I have is P/N 3431647 that did come off of a '74 B-body. So if the latter part number will not work, is there an E-body drive arm counterpart from '74 that uses the poly bushings?

Thanks for all of the info!
