Yes the hexagon plug (1" AF socket size) is about half way up on the drivers side it also acts as a level indicator so fill until it starts dribbling out of the hole. There is a copper washer under the head of the plug but you can anneal the old one by heating it up to red hot then quenching in water. And another yes is to use 20-50 oil to top it up.
