Transfercase seal leaking

so i recently purchased my evo 9 a few weeks ago and today as i was changing my oil i noticed a small wet spot between the transfercase and transmission. i checked both the trans fluid and t-case fluid and noted that the trans was filled to the correct level however the t-case seemed a bit low. this leads me to my conclusion that its the t-case thats leaking. i called up the dealership and asked about the seals that i would need and he told me there was 3 of them so i said ill take all of em just in case cause i dont exactly know which one it could be. I remember doing a search and i found a thread listing the exact part numbers for the seals i would need but i cant seem to find it again. anyone have a link?
ill be removing and installing the t-case and seals myself, i read the writeup and watched a video from boostedfilms.com about it and doesn't seem like anything i couldn't do myself, just takes sometime... my question to those of you that have done this is how long did it take you to do this on average? ill be on jackstands in my backyard.

If i can find an exploded diagram of the five soeed trans maybe it would help me get an idea of what seal could be leakin. Only thing that could come to mind right away is input shaft seal?

No one wants to chime in here? Ive been searching guys but pretty much everything seems to be related to t-case (which is what i thought the problem was) and axle seals. Could it be that the actual seam where the tranny and bell housing split thats leaking? Im not having any luck finding that diagram.

It's not coming from the drain plug, right? Appears to be too far towards the passenger side for that. I'd have prefered that.

so what. take it apart and replace the seal. inspect the case for cracks while there and weld it if you find any. looks like you would need to take it off anyway.
