the obs t-case will bolt up to the 4r100 the bolt patterns are the same the variables will come into play are the outputs so you can use your driveshafts. The other question will be the electronic shift shenanigans if you have them.
The SD transfer case is a higher power rated model so if you have access to the OBS case cheap to get you on the road then it is an option if the shafts will connect.
