Had to notch the top com support bracket so that 4.0x10mm countersunk rivets would clear on both sides. Also dimpled the five holes to match skin dimpling for parachute option (was not in instructions).

Took some material off right side rear seat belt attachment bracket so that it would not protrude out and interfere with skin. The left side had plenty of clearance.

Took some material off both right and left seat belt support mounting plate so it would not protrude out and interfere with skin.
