Yes. It's 1-7/8" and it's exactly what I did. (and several others on the board.)

EDIT - wait you're using an NP203 or NP205?? Still in theory you should be able to do it but I just took out a TH350 for a 700R4. the Tcase was still the stock NP205. I also used the Advanced Adapter output shaft so I could mate the new trans to the OE Tcase.
