Wiper linkage questions 67-9 cuda

Steve, Heres pix of what's out of my sons car. 69 barracuda. Not sure it was ever pulled apart, motor was gone when I got the car, as was one pivot. I got another replacement wiper arm pivot to make it complete. It came with really crunchy motor compartment wiring that was wired for a 2 speed. There was a green splotch of paint on the crank arm. I dunno if that was an assembly line identifier or not.
