The manual calls the clip a pin lock
Part number 359380
...click... You will have to do some research. But chevs of the 40s offers a similar clip for large truck brakes
Part number 359380
...link... This is not listed as the clutch/brake pin lock
It may or may
not work
If someone has a brake/clutch pin lock removed maybe they can measure the o.d if its 1 3/16 its probably the same part?
Otherwise maybe try a e clip
