I did finally get it out- one thing I noticed was some of the screws have blue Loctite on the threads. I guess they figure it’ll get tossed around. This underscores the importance of having the correct tools and making double darn sure you are using the correct size, etc.

I tried my JIS 000 on Step 5 and was unable to get the screw to budge. It’s partner from the other side came right out with no trouble. Don’t really want to narf up the screw, so I bailed out. Anyone else have this issue?
