just a small piece of advice for getting the regulator arm 'balls' out of the plastic clip, I found taking a rag or piece of cloth and wrapping it around the arm, then getting it as close to the bottom of the arm (where ball meets clip) as you can get and giving it a good pull will pop the ball out a little easier than just using your hands.
Mine is for sure going to break again soon, so this write up is going to be real handy!
thanks jess!
