The 1940 adjustment screws are 10-32 X 1-1/4"L as measured from under the second head, made of steel with a slotted pan head. Would be easy to solder a washer under the head with a gap of 1/16" between the two heads.
This is exactly what I was thinking after inspecting the larger screws I removed from the '50 buckets.
