2001 Front Diff fill plug location??

[lookn4runr]

Switched over to Amsoil in the rear and transfer case, but il'l be dipped if I can find the fill plug for the front diff... Found the drain OK, but no fill.
Thanks!

Fill is on the driver side about the same distance from the rear of the diff housing as the drain. It's somewhat obscured by the drive shaft, difficult to access, but doable.
