Intersting to note that the heavy duty steel brackets that are needed to hold the engine mount in place are not mentioned until Chapter 17. There is a small area of these brackets that covers a rivet hole on the front wheel upper bracket. Skykits says its ok to file a small relief cut.
Note that the horizontal brackets SF233/4 are in wrong in this picture- too far out
Mujst be placed tight against FW and the extruded angle drilled accordingly
