More avionics mounting

Since I had moved the essential bus bar one hole lower, I added the new bottom hole and nutplate (keeping the top hole for the fuel pump relay):

I also added nutplates for #8 screws to hold the main wiring harness through adel clamps, underneath the right side flange:

For attaching the Bus manager, I used two of the same holes that attach the ECUs, plus another pair of holes for AN3s, and added nutplates (the plastic is pretty thick, and I used soft rivets for those) (I also had no L4 nutplates at hand, so had to order those):

Last but not least, I trimmed the side of the mounting angle to allow airflow out of the Bus Manager:

I finally obtained a CO Guardian 455, so I had to cut a hole for it on the bottom center insert - I laser-cut a template out of acrylic, then used that to cut the carbon fiber + metal insert:

I had to slightly adjust the bottom center panel for that to fit:

For mounting the GTR20 radio, I made a custom mount similar to the one Vans provides for the wingtip strobes, which lets me mount it in either direction, and attaches to the side of the tailcone:
