I've just traded both of these items in at AW Transmissions - both from a Discovery. (1:222 T-box)
I can always ask what he wants for them after he's reconditioned the pair of them, if you like?
I have a gearbox that needs a home. No transfer box though.
Was a good one covered 130k had a slight crunch into second when cold but fine once warmed up.
Gimme a shout if your interested could even give you a hand fitting it as your not to far from me.
