If you want to attempt to save a little cash on a bad screen on your Billet Box, I just went through it and decided to make a video: Replacing Billet Box screen. It’s not too tough, just a little tedious to do with bad eyesight.
Sorry for the poor quality video, I am going to look at getting some better equipment soonish.
If you want to let someone else do this for you, look up Jeff Coutu from Mechanical Therapy or Randall Tufts on Facebook.
If you want to avoid causing a bad screen due to replacing inners, we have a video for that too!
