Not sure what 6 speed manual box is in the D3 (mated to 2.7 diesel), but there is currently one manual D3 up for salvage on Pickles.
I believe there are adaptor kits out of UK available to mate that 6 speed box up to LT230 transfer cases.
AS for the front end, I suppose it depends on how large the bell housing is on the D3 box, to be able to fit the TD5 flywheel.
