Hey falldowngoboom,

Thanks for the check. My mounts are already mounted to the firewall so I'm not going to offset there. (Your right but I hadnt thought of that)
I made the mounts wider than the engine by a little less than 1/16" then centered the engine and drilled one hole to hold the engine in place.
This leaves a little wiggle room to rotate the engine.
I'll make a 11.75" and a 10.75" brace between the LE and the ends of my aluminum " prop ". I'll clamp everything in place and then drill the holes.

I have to check at home but I believe your numbers will reduce the amount of rotation I'm showing in my photo?

Like I said it looked like alot visualy they way I have it now?

Steve
