Prop Flange Measurments (0-320) for Prop Design

[Xkuzme1]

I'm trying to help a company design a new prop for RVs. Working towards a ground adjustable 3 blade prop. I've taken many measurments from my 0-320 D1A but I'd like some backup.

I'm looking for a precise drawing with specs. I've attached a couple drawings as examples.

Can anyone help lead me in the right direction.

Thanks guys!
