CO: D shaft clip
Here is why i disagree with post #5. The 3 speed, and V speed knobs have a larger diameter shaft. They use a retainer as you have described. The 68-72 two speed has a smaller diameter shaft. It uses a piece of spring steel shim stock in the slotted hole. Note the yellow marking in the pic below. I would know. I have a 69 2 speed setup with the knob on the left, and a 67 V speed setup with the knob on the right. I believe the 73 and up 2 speed switches went to the larger more common 3 speed shaft. Woulda been nuch easier if they made all the wiper switch shafts the same size.
