Where is the dana 60 breather valve?

[us74k5]

Just as the title says... I cant find the breather valve for my front dana 60 (came out of an army truck). Anyone know where it is, or have a pic for me? Thanks.

doesn't matter if it's an army axle. all the same thing. when your looking at the front of the axle. i think it's on the left side of the diff, towards the top.
