Good luck getting oil into the center section, may be try it from the drain end.
The bolts are 10mmx 1.25, I got mine from the dealer, may be it's just me but for this location I'd rather have OEM strenght and heat range bolts. I have no idea if that matters but I just feel safer when I remove them next time.
HINT, Anti-seize compound is your best friend.
