Hello! How's the truck progressing. I picked up on a couple of things. On the 3rd picture you posted, you have labelled one large nut & bolt 'Fill port'..... The fill port and level port are the one you have labelled in the second picture that are on the tin cover on the front of the diff. The one in picture three is an adjustable 'pin' that sits just off from the back face of the crown wheel. It's there to stop the crown wheel pushing outwards away from the pinion when under extreme load, (Pinned diff) so prob don't touch it unless you have too to stop the small leak.
Also on the picture with the transferase, you have correctly pointed out the fill point, but the lower plug is the level plug, putting the full oil level level or just below the tail shaft output seal. Hope this helps.
