no filling plug on lt77 box ?

[uglymug]

Why haven't I got a filling plug on the side of my lt77 box ? Big drain plug at the bottom but just a blank casting. Not on the other side either. So how do I fill it then ? How much to put in as some say 2litres but Difflock say 3litres ?

hi , box is on the bench anyway, so will tip on its side to fill. By the way it is joined to a 390se NGK engine.....

there seems to be a breather plug in the top part. Have ordered 2l of Difflock so will fill thru drain plug....................

hi , yes seen that but thought not to touch as could have spring/pins for mechanism underneath as have always in the past filled up by square headed bolt on the blank side. Just had a look and can fill thru this hole when gearbox is in the car. Anyway thanks to all for your ideas...........ta like
