There are two trouble spots. Both on the front part of where that hump is. You will break through the housing around the 1 o'clock area when you're looking into the throttle body. When looking down on top, this area is the spot between the MAF mount and the lip of the TB. You can deffinately see it. The other spot is where the screw runs down in the 11 o'clock area for the front of the MAF. A little bit of epoxy in between the first area will take care of the problem, and then a little dab from the inside into the thread, but not too much or the screw will push it right back out, and then you have the potential for a leak.
