I’m not much use, I’m afraid, because I had thought that all the L322 transfer boxes were interchangeable.
However, I can see your dilemma. JPAT (near Bristol) sell spares for the DD295 and their catalogue appears to identify two different input shafts.

One is for transfer boxes with part numbers:
IAB500240, IAB500241, IAB500243, IAB500244, IAB500280, LR006016, LR008206
and the other for transfer boxes:
LR023011, LR035617, LR045477, LR049160, LR052611, LR089531
This also appears to be confirmed by Sussex Autos, who further state that (exactly as you mentioned) the earlier shaft is no longer available :

I wondered if it might be worth you contacting either of them to see if they can tell you what the difference is? I notice that the Sussex Autos price for the later shaft is £182.65 incl. VAT. Second-hand DD295 transfer boxes commonly appear on eBay from around £150. Obviously, there’s a risk buying a second-hand box for spares. Any sign of brown dust (fretting corrosion) on the spline would clearly rule it out. The gamble would be that if the splines were lubricated at the factory during assembly then the input shaft internal spline should be fine on a second-hand unit.
