I just got a new rear end in a pile of parts. I want to check the ratio, but can't find a drain plug (it's a 10 bolt). There is what looks to be a drain plug on the front left side, but the little cap on the end of it only spins. It almost feels like it's made of plastic. Do I have to pry the cover off to drain this thing, or am I missing something? Thanks for any help.

Your lack of preparation is not my emergency
