Final measuring and drilling the attach holes for the throttle quadrant structure.I used 8R8 screws and will install nutplates (probably on the angles side)

In the next image, I also drilled the vertical part of the larger attach angle on the sub panel

 Back side. Now that everything is defined, I can mark the exact length of the angles and cut them of.

This is what the structure looks like off the airplane.

 Reinstalled and cut the angles to length.
