Installed upper engine mounts & longerons. Didn't have the edge distance for the 3/8 bolt on the upper right mount so I took it to Just Aircraft and they welded some 4130 to it then I shaped it to fit.
Check angle on the firewall and leveld the longerons fore, aft, left & right.
Plans call for shims under the lower mounts between the firewall flange and the pedal channel. This would have only one bolt going through the shims so I added an extra bolt to each lower engine mount. There was plenty of material for this to still have lots of distance between the bolt holes.
