need windshield wiper help

[cdub2010]

My wipers are currently parked at 12 noon. a little background

1977 gmc truck with a updated intermintent wiper switch setup with a newer motor i dont remember what year it is. It all works its just that it parks the blades at 12 noon and starts going counterclockwise so I cant just clock the arms to fix it. A few pics to help.

Not im not really to bright so do I cut and weld the wiper crank arm bracket? Is there another bracket I need to get
