Name that 'box.

While searching eblag for another 'box for mi series I came accros this, have no idea what this is, the prop shaft looks deffy, the box looks lt77 but has a fairy overdrive on the back, and the bellhousing doesnt look series.
Maybe first deffys or series v8 petrol.
Sure someone reading this knows.

looks like an old rangey box

guess at 4 speed rangey too

stage one box to me ........

So is it a v8 then?
Any use for a series, one that has a disco fron axle.
