Whoops!! Not a typo - a mental lapse. I have a habit of crossing 5/8 and 9/16 when doing decimal equivalences in my head ;-) So:
Face width on the 9/16" gears should be .561/.562
Face width on the 3/4" gears should be .724/.725
Note that the 3/4" gears are actually a bit narrower than .750. I do not know how they came to be called 3/4" gears but that .724/.725 width is straight from the original Ford prints and I am quite sure it's a good number.
