This is not exactly your case, but it may help. I put a disco xfer case (auto) in our 95 d-90 (manual) and everything bolted right up and fit perfectly. The one thing that is different between the two cases is the shift-lock solenoid. It is only on the auto transmissions and it simply prevents you from shifting the t-case unless the trans is in neutral. t-cases from manual trucks don't have this.
