Where did you get that long bike cable? How long is it? Is it for gears or brakes?

I was planning the same type of "slider" block in the lower grille of the Insight. One thing I had decided was to make sure the "track" is straight. If it bends/curves at all, you will get friction against the sliding part. That means I have to mount a "flat" assembly in a "curved" grille space.

I was considering using 1/2 inch aluminum angle to make the frame/track. You can get that at Home Depot.
