Good pictures, M!ke...Scifi, the lever seems unique to the popup headlights. I actually started trying to make my own from pieces used for a parking brake, but the push-knob is pretty special (and follows the same industrial design as the knobs used on the seat rail adjusters). Pushing the knob releases the latch at the bottom (there is a single upright position for it, unlike a parking brake that will have progressive pressure). Note also the swivel at the front of the cage.
I used 72" and 90" control cables (for left and right).
