The only explanation for the different drain plug is that the last person who changed the fluid cracked the case. It could be a hairline crack. When that happens, the only option is to adapt a bigger drain plug or change the cover. As long as there’s no leaks, there’s nothing to worry about.
Good job overall. Your oil looks very clean actually…. I cringed a little bit when I saw you torquing the plugs. The plug is tapered and torque is perfunctory, which means the same applied torque will introduce uncontrolled force into the plug hole. This is how I cracked mine. I think you are OK with magnetic plug, but these transfer cases drain area is very weak (aluminum). Tightening by hand and 2 or 3 turns will do.
Thanks for the feedback, I had the same fear as I started to torque the drain plug, I was not quite getting the 15Nm and it felt like a lot of torque for an aluminum housing that is why I stopped it a little early and certainly the fill plug (allen key with no head on it), I stopped once I got about 4 or 5 of the thread locked threads in (i.e. I did not wait for my torque wrench to beep at 15Nm).

@@1000raulm thanks, that makes sense, I checked it after a week of driving an no leak. 🤞
