Can someone tell me the torque values for the front and rear differential fill and drain plugs?

Also, I went to the dealer and bought new "washers" for $5 each!!!! Any suggestions on another option? That is just stupid for a piece of plastic. Does Autozone or Napa carry replacement washers that will work?

thanks
