OK so I know nothing about what's inside the air box assembly. I'm having hell trying to get that broken off piece out. Am I correct in assuming that I should be able to just push it down inside and it will just fall into the bottom of the box, or is there a little recess there, so if I push it down it becomes jammed in there and I'll never be able to use the new part I bought?? You can't see what you're doing, there's only like 1" of clearance on top of it, and enough of the piece broke off to keep it from just falling in, but not enough to grab hold of and twist out.... blah. I walked away before I broke something.
