Companion Flange Nut Size

I'm getting ready to re-do the seal on the rear output shaft of the t-case and want to buy a socket for the nut that holds the companion flange to the shaft. (I borrowed a socket last time and that door has since closed). If I recall correctly, the size is 1-5/16" but would like to confirm that before I order. I'd rather not take the driveshaft off just to measure.
Thanks.

Yep, 1 and 5/16ths-I fit it to my spare transfer case just to be sure.

Thank you very much Gary. Spare T-case, huh? Are they that unreliable? Just curious, what do you think it weighs? (If I can't stop the leak I may be looking at removing and rebuilding as there may be bearings or something wrong internally.)

Sure thing Warren! It's heavy-I'd say close to 200 lbs. Mine is on my spare creeper just so I can maneuver it around. T-cases blow due to lack of oil since there are so many seals that can leak, and I got a spare because my original has to have been as abused as the rest of the drivetrain (no maintenance, etc.) That's one of my winter projects-swap that T-case....
