Transmission and t-case are in. The transmission went right in like it belonged there! The BW1356..... Well that took some work. Lots of hammering, grinding, and cutting. I'm not entirety happy with the way I had to make it fit, but it is what it is. The problem was that my radius arm cross member was right where the t-case is, so I had to make the t-case NOT hang below the frame.
Here a passenger side view of the trans, notice the header is now 3/4"+ away from the frame
Another passenger side view, here's the t-case. Note its not in its final position yet. Also I removed all the heat shields from the cab for better fit.
Here's a few pics of the back of the t-case, notice I had to cut away at the rear cab support bar. I notice no difference in strength from within the cab.
Here's why I'm not super excited.... I had to notch the frame

.I took about 5/8" off of it on the top side. There's still about 1 1/2" of the frame left, which is plenty for strength purposes.
Passenger side view, plenty of room for activities!
Here's where my interference problem is. Once again this is not the final position, its going to be moved up and to the passenger side. If I jack it all the way up against the floorboard its about 1/4" above the bottom of the frame rail. So my intentions are to get it really close to the cab floorboard, and modify the cross member a little bit. Basically I will just cut slits in it, hammer down thoses slits, weld it back, and reinstall it. This should give me about 3/4" clearance on the bottom of the t-case. Note how I grinded away every little bit I could, Lol
Also I got the computer mounted in the firewall, my aluminum box that I made wouldn't work, so I hacked it up, cut the hole in the firewall and made it work. Looks decent.
There's still time left in the day, I might try and get the cross member modified. Pics to follow
