Hi Howard and Joz, Maybe i have missed something, i have two of the 016 4wd boxes in my garage and the awd box is exactly 180mm longer than the 2wd, i have not been able to figure out how the rear section comes off, does anyone know.It is not like the 2wd with a large nut behind the rubber bung.
It would appear from looking at an exploded view that it is possiable to lock the centre diff with the mechanizm at the rear and so send all the drive up the hollow shaft to the pinion shaft.The rear flange will still turn in sync with the driving shafts.
Regards
Lambo
