FYI...This is the extended Torx set I found which also includes the T-40 needed for the plenum bolts. Although this may be common knowledge among the seasoned members, I would suggest a purchase of this kit or a similar one for those members thinking about doing their first plenum pull. The extended T-40 will not only fit in those two tight spaces mentioned before, with ease. But you will now be fully seated in the bolt during disassembly and when putting the correct torque on these during reassembly. And not have the fear of stripping out the head of the bolt.
