Since I have no reason to remove the belly pan at the field I chose to reverse the mounting method. Screws from the top. First problem was to remove the already glued in blind nuts. I made a puller out of a piece of 1/2" CF tube goes around blind nut, and a piece of 1/8" CF with a 6-32 screw through it. Easily pulled the blind nuts out wothout damaging the landing gear plate. See first two pictures.

The blind nuts were then relocated to the bottom of the gear. Drill the holes out to the right diameter and glue them in place. I cut the prongs off the blind nuts first. You can push them into the CF gear with a vise but it doesn't always work.

Mount the belly pan first, then slide in the gear and attach from above.

Next step will be to install the fuse former, rudder tray and firewall. I can already see that the rudder tray will be an issue.
