Damn, that's super high for a drain plug IMO. Now I remember having to lift the darn car to break the plugs loose, so those torque numbers might be right. If you're not familiar hand-torquing drain bolts (I've been doing it for decades, and never an issue), I suggest you use the factory torque specs. I also tried the search function to help you out, but it SUCKS on this site; couldn't find anything. You might want to specifically ask for that on a new thread, with the added benefit future members can easily find it ('Need torque value for differential fill and drain bolts', or something like that). Good luck buddy.
