I am doing the octopus hose. I got the supercharger out, and it looks like it would be more convenient to remove the bracket than to snake the hose through it. There are two bolts at the top (which I got out) and two studs at the bottom (ones with dowel pins). I can't seem to get the bracket out. Do I need to remove the studs? Or do I just need to give the bracket a gentle whack with a rubber mallet? Are there bolts on the bottom that I missed?
