Can anyone help with official dimensions for the flywheel bolt pattern (crank rear flange).

Page 49 of the Power Source Manual gives the offset hole as being offset 5 degrees (and the others equally spaced) but does not give the bolt circle dimension.

I know I can measure it but would prefer an official dimension.

Anyone help?
