RE: Measure Right Thrust
The right thrust is built into the firewall of that plane. assuming the plane was built straight the first time, the crankshaft at the hub should line up with the center line of the plane. That plane produces alot of torque and p-factor, so even 2 degrees is not really enough but any more the that makes the plane look odd. right thrust is a convenience but not required. The red box P-40's did not have any right thrust and flew fine. You will need to know how to manage the rudder on that plane. Good luck in you rebuild and keep your CG forward.
