I've been running it since I posted this - no issues. DIY for DIY-people. I'm not sure why you'd want it to be adjustable either - this pretty much eliminates all of the excess travel at the end of the pedal, why would you want more?
adding some nuts would make it completely adjustable for a few more cents though.
@bas2000 - the 1/4" x 1 1/2" elevator bolt fit pretty well for me (as you can see in the picture). Post it up if you find a bolt that fits better.
