Expanding holes to allow engine mount to pass through firewall and contact fuselage

The firewall is not sandwiched between the engine mount and fuselage, instead it is mounted via tabs to the fuselage. The holes where the engine mount would come into contact with the firewall are expanded slightly to allow the engine mount to mount directly against the fuselage.
