not sure about measuring from the gear down..but maybe the clip depth measurements might help you a bit:

(note; this was based off retaining clip install hight issues...this may not give your enough info)

as meassured from end of shaft to bottom of gear (oil pump drive end) is 1 1/2" on 88 crown vic donner car

1 " on older distributor i had

dist shaft is also smaller diameter on vicky one

cant use thick film dist.
running carb and need mechanical advance (drag car vacuum not needed)
