Some questions on high-lift transmission gears. Please help?

Question 1, gear pitch of the final 3 gears of the high lift transmission?

 

I've been trying to measure the gear pitch of the final 3 gears and it seems I more or less reach the number of 0.96 module, which does not make sense as the closest gear pitch is either 0.8mod or 1.0mod. So to be sure I tested against a known gear pitch (1.0module) on another short course truck, and it seems to match. The thing is, I can't be sure so I am just asking for confirmation or corrections if I am wrong.

2nd question.

1 of the ways I am trying to modify the gear ratios of the HL tranny, is to get a replacement gear for the final gear, the one with a hex slot in the middle. How do I find 1.0module gears with the same sized hex hole?
