Located in your Parts Catalog it shows the same part # 103815 for the Engine Oil Drain Plug, Auto. Trans Final Drive drain and fill Plugs, and Auto Trans. Autocase Lower Pan drain plug. So, Yes they are the same. 8 mm square female hole. I found a square key 5/16"x5/16"x1-1/4" works pretty well and turn it with a crescent wrench. Please review MY post # 16298 regarding the oil drain plug removal tool. And read the very bottom of the same message. The Manual Trans. Gearbox Casing drain and fill plugs are part # 103016. This is a 10 mm square male thingy. John Hervey of www.specialtauto.com makes life too easy. From him you can buy a hex head drain plug (S.S. or Brass) and not have to screw with making your own drain plug removal tool. Mark R.
