I believe the firewall is set at 2 degrees right thrust and the thrust washer is 7.5 inches from the firewall. It would have been nice if the firewall was marked for the airplanes thrust line but that wasn't done. So in the interest of not haveing to guess I thought I would ask the experts.

Status: offline 		Thank you Bill, I had talked with Helmut and Dymond and he told me .25 up and left and that worked perfect, so I think your .26 would have worked great. thanks again.
