I don't know about the 67's, but my 68 motor didn't work, so I drilled out the crimps (as directed in the service manual)and repaired a broken wire. Also had to do some work on the park cam and contact (the copper contact arm had bent). On my motor there are 2 marks on the housing 90 deg apart, and there is a mark on the arm that connects to the oscillating arms driving the wipers. These marks must be lined up properly. When I first put it back together, my wipers stopped in the middle of the window. I checked and found that I had misalligned the arm by 90 degrees. Don't know if this is your problem, but I would check it before buying a motor.
