I see now how it needs to go when flipped. After closer inspection, I'm the first goon in here. It isn't as complex as I expected it to be. I don't anticipate any problems if I put it all back together in reverse order. I didn't damage the gasket, but I do have a new one from treats for a backup. I'll torque it proper, and check end play float.
I think I was more scared of it than I needed to be.
