Liking the progress. I would seriously reconsider the divorced case and a rear tank. Besides keeping all those ujoints happy, and relocating your fuel tank, the Front Driveshaft will likely hit the tranny crossmember and will require a serious rework. I know that with a welder all things are possible but often times the juice isn't worth the squeeze. Additionally, mounting and plumbing the rear tank is easy, filling it is hard. You choices are inside the van, inside the wheel well, or cut the body. All have their drawbacks.
You've got your work cut out, I wouldn't reinvent the wheel with the 4wd conversion. If you get a 4r100 from a truck, get the Tcase from the same truck. Some had VSS's in the tail housing, some in the TCase. Im running a truck tranny and it works great.
Yeah the more I look at it the smarter part of my brain says get a 4r100 and t-case from a truck and get it rebuilt with upgraded parts..that way Im not stranded somewhere in 2 years because I was in a hurry and stupid...LOL
