... and I also used the double-nutting to remove the ~8 studs that did not get pulled out when removing the nuts. Cleaned them up, etc. as with all the others.

For me, those nuts look like they're Copper, but were definitely Copper plated Steel (as proven when dropped in my magnetic tray). Pretty cool. But as I found, they still stuck on many of the studs. The main reason I used the anti-seize was that knowing how difficult it had been removing them, I wanted to do everything I possibly could to make reinstallation easy.

Also, if you use threadlocker like I did when reinstalling the studs, make sure you clean all the PB Blaster you used off. Adhesives are only as good as the stuff they stick to.
