If you find something please send my way as well. I am just sitting here scared to cut into the firewall. By the way has anyone else found a problem with clearance of the the control horns on the rudder in reference to the rear of the fuse? And also the length of the screws to mount engine on the mount itself? Some hardware just doesnt seem right. May just be me considering I dont know what I am doing.

In the picture you will notice in bottom left corner the marking where the muffler has to go. Any help is appreciated!
