I just use a rule of thumb to use as big a pin as possible to fully occupy the bolt hole, the pin head expanded into the nut slot, then trimmed to length to bend one arm down the side of the nut, the other arm up and across the top of the bolt.

I don't guarantee accuracy, but the Fahnestock book has a
cotter pin list that's mostly correct.
:D

Looking @ past posts, I did not see the specific pin for the output plate listed.

Per Bruce's CD parts listing, the cotter for the clutch finger adjusting screw is Factory No. 757 , as shown on the cutaway drawing.

Cotter pin, 3/32 x 7/8". Clutch finger
