You are correct ... as I also noted in this post, the veritcal dimension for the hole in the "motor side" plate is .734 (which is correct) while the dimension for the "same" hole in the other plate is .810.

Also, I chose to use the 56 tooth gear and adjust the center distance to maintain proper mesh at PD. However as Dave has mentioned a couple of times, the 55 tooth gear is correct and can be ordered from PIC by substituting a '55' for the '56' in their part number.
