My engine mount, which i am almost ready to install is an original Brock mount and my project came with a brand new 0-235 L2C. I would like to replace the upper 1/8"aluminun 1''x1" excrusions with 11/2"x1" to accept the 0-320. After doing this, I would like to stiffen the mount frame with gussets but have no idea where these are located and the material that is used. If someone in the group has a picture or drawing of what I should do, please let me know, and thanks for your time. Rick Bell Victoria B.C. Long-EZ #032 under construction
