I'm looking for some sizes on the propeller hub and bolt circle the dia.
fore the bolt holes or bushing.
Also the thickness of the flange.

I f you are going to around 200HP or more you will need a 7" Flange and
crush plate and 7/16"or 1/2" bolts. Quote from Laurie Prince.

Ian Beadle Renesis RV7.

Won't hurt to use a SAE #3 but
I think she is thinking 4 cyl Lycoming IO-360 which has much worse torque
pulse than a geared rotary. As far as I know tracy does not seem
to have a problem.
