(Below, the green one is phlpp's pauldron and the other two are the new ones, i cant see why they wont fit. )
(And i didnt delete the original Kozane pauldrons, i added about 32 more with different combinations of pauldrons and body parts, i only altered the original okegawa,yukino****a,nuinobe,hishinui armors added about 3 times more combinations, goal is to make soldiers look more unique with realistic pauldrons and armors.)
