help needed with 904

Okay so here's my latest dilemma I was able to get the first second drum together I think ok. Now I'm on the third reverse drum and it's the interseal that's giving me the hard time. I'll shoot a picture here and the inner seal that came out as the bottom right one and the one on top of it is the one I believe that matches it and the other two to the upper middle and left are the closest ones. I can tell on the big outer Seal there seem to be substantial wear on the seal either that or the new ones just bigger in exterior circumference. The outer seal with the ridge facing down fits fine without the inner seal, even though it's bigger than the old one. but the interseal was almost non-existent. It didn't protrude out much whatsoever and I can feel that this fits very tight on there on the inside. Either that or this is just the wrong seal?
