1. Removed the baggage door. 2. Marked the door and the cross-cabin firewall brace in the baggage compartment for the locations to be drilled. 3. Drilled three #30 holes in the right side of the baggage door for LP4-3 pull rivets. 4. Drilled #19 holes in the brace, then drilled the attach holes for two #8 nutplates. Countersunk the attach holes and deburred everything. 5. Riveted the nutplates in place. 6. Screwed the lower fitting of the lift strut into place and checked its fit and orientation, and verified clearances from the edge of the door opening. 7. I stashed the strut inside the baggage compartment while the painting takes place, and I'll rivet the upper end to the door later.
