Are these the transfer case fill and drain bolts?

aldo, can i use the same hypoid gl5 oil i used for the rear diff/transmission here. what quantity does it take?

 

Yes.

Break loss the fill plug first. You want to make sure you can actually fill before you start draining.

 

Is this stock or is this a pieced together 4wd swap? If its a swap, I'd figure out what year that transfer case is from and look up what it takes. Not sure if the older transfer cases were using GL5.
