S90: Airbox #2 Continued

I'd almost given up on the second airbox, since it seemed impossible to get the stuck screw out without also damaging the tab itself. 

But once again, the 4-week break from wrenching proved useful for problem solving.  I'd realized I could just clamp the tab down to provide enough support to take the hammering from the impact driver.  So I threw two clamps on the tab, then put the clamps themselves into the vice and Presto!

With just a couple whacks the screw freed up, and I turned most of it out by hand.  Plus, the tab actually got bent back in the right direction and looks pretty close to where it ought to be now.
