OK, thanks guys. I was fairly certain it was a 1354, I found those numbers stamped onto a few internal parts as well.
May have run into another problem. Look at the second to last picture, on the far right hand side. See those cogs? See how they don't quite line up? That is in 2wd, so the top cog shouldn't be engaged, and it isn't. But the outer part could be quite a bit higher, and it still wouldn't be engaged. When the case is put into 4x4 the outer cog only moves up so much, and while it is enough to engage the cog, it's not all the way up it, only the bottom HALF of the cog is engaged. I fear that I may be missing a spring or washer that lifts everything a little bit. In fact, I think that's what caused the broken mode fork. The difference in height tweaks the mode fork just enough that it can get caught and bind.
I'm not sure I'm the first to crack this case.
Has ANYONE else opened one of these up? can you tell me if your cogs lined up closer then mine do? Maybe the spring is in there, but there is too much weight pressing down with the gears and chain on, but once I turn it sideways to install it the spring will push everything back in place.
Glacier, you started opening up one of these 2 years ago. Any picks, still have it? Want to crack it real quick and look inside for me?
I don't want to take EVERY little piece out to count them and compare to the diagram, to see if I have everything. You can't even buy most of those little parts anyway.
