Heres the oil pan from the M113K. Me and my dad kind of went in blind since were both more a do it type. We were worried since the the S has one oil pan and we werent sure about how it would bolt in. Where it bolts in to hold the pump has the same same bolts but hollow and it stays with a screw on top of it so we just switched the bolts. Its really cool actually i havent seen that before.
