Re: 700r4 4x4 swap

NP 205 never came behind a 700R4, so you will need an aftermarket adapter. Maybe Advanced Adapters makes one. Then you will need to modify both driveshafts. I think your front will be too short and rear too long. Then you will have to modify the cross member that the tranny and transfer case bolts to or at least move it's location to fit the new combo.

It can be done and has been done, but it takes some work to do it.

That is a pricey adapter kit. Last one I saw went for almost $500.00 and you have to change the output shaft in the transmission.
