Dana 35 IFS pinion nut size?

[Nihil]

I'm replacing the seal on my 99' Dana 35 IFS tomorrow and the only thing I can't find is how large the nut is for the pinion. Don't want to start and realize I don't have the correct socket. Thanks.

Should be 1-1/8"

Thanks. Ran out and picked one up. Now to hope for it to break 40 degrees tomorrow.
