For the 4L80E you can use a custom adapter flange to fit the 2-wd trans to a T-400 NP205 transfer case and adapter housing. Take a look at NP205.org for this.

For mine I'll be sticking with either the original TH350, or using a 700R4. I don't want to swap out the original gauges. Either of these two will make the swap simple and inexpensive. Staying with the TH350, I will only need the spacer ($32). If I go with a 700R4, I will still need to spacer, but the trans will be cheap, and I can still keep the original gauges.
