Now with the front panel off, we can see all the parts inside. Note how the a-arms on the rear are all held in place with all-thread. This kept the a-arms from flopping around. The whole assembly was quite sturdy. The rotors were bolted to the bottom of the crate. Removal of the nuts on the bottom facilitated removal of the assemblies from the crate. The front a-arms are tucked on the outside edges and in between.
