With some careful hand bending the aluminum tube between the wiper motor and first transmission was fit into place. The wood frame was cut out as needed to keep the tubing tucked away and not in the way of any interior finishing. Upon final assembly, the tubing will be epoxied into the cutouts in the wood frame to keep it from moving. The right wiper transmission was located and installed in the same manner.
Second and third pictures show the before/after wiper drive shaft and threaded post installation. Post and shaft were cut off according to instructions.
