BW1345 T-case Yoke nut.... special tool?
 

I'm trying to get the yoke nut off of the rear main yoke on my '86. Any body know what size the nut is, and if there is a special tool to get it loose? The nut in the center if the rear facing yoke on the t-case, that is the one.

Thanks in advance.

Nevermind, I got it, 1 1/4 12pt thinwall socket works perfect. Got the yoke off with the air impact.
