I just pulled the HD Stage 1 air cleaner and mounting plate off of my bike, as I'm going to install the Stage 2 Big Sucker. I like the larger mount and tubeless design. Behind the HD Stage 1 mounting plate was a mounting bracket that came off with the plate. Is this mounting bracket the same thing as a throttle body support bracket? I don't think it is, as it doesn't sit in place by itself and looks to need the mounting plate to do so, so I was thinking that it was a part of the HD Stage 1 kit. I wanted to be sure as the Big Sucker install directions state that the Throttle Body Support bracket is to stay in place. Below is a .PDF supplied by Glider in a previous thread where the part listed as #10 on page 3 is what I am referring to. Stage 1 - 5.pdf Thanks.
