I just received a new engine mount ordered from Steen Aero for my AEIO-540 to be mounted on my Skybolt build. I am test fitting the new mount to my fuselage and engine. Fuselage side fits the mounting holes, but I cannot get the mount to fit the mount points on the engine side. I can get the top bushings in place with a bolt in but the bottom right side appears to be about 1/4" off center of the Lord mount holes. My previous mount was the same way and that's why I ordered this new one. Am I doing something wrong? I am sure Steen Aero uses a jig for the engine side and they should all be the same, correct? Somehow I think it is installer error but for the life of me I cant figure out what is going on.
