Tonight I worked out how I plan to mount the GEA24 box. This will mount directly onto the sub panel, with a doubler on each side to support the nut plates and provide some additional strength. The box itself is not heavy, but with the cables attached it will be heavier. It also needs to be able to withstand repeated +6/-3 G loads without cracking, so I want the mount to be strong.
Space on the forward side of the sub-panel is tight on one side, and open on the other. I made up to backing plates, the drilled, countersunk, and primed them.
