f8
Here's the rear rod retention mechanism: f8 is a carbon fibre plate with two very sturdy aluminum mounting brackets attached. Four screws that go through these aluminum brackets hold the rod immovable.
The c/f plate may need a small amount of adjustment (by sanding one or other side) to ensure that the stab is perfectly aligned - both in terms of stab incidence, and in ensuring that the stab anhedral is symmetrical (check against the wings)
In the middle of F8 you can see an S-shaped rod and balsa block - this forms part of the retention mechanism for the removable rear nozzle.
