200DI conversion

hi all?
picking up a 200tdi engine in a week or so to start conversion from my 2.25 petrol.
for a few extra notes the seller has offered me the gearbox and tranny (disco 200tdi)

I was gonna bolt engine straight to my series boxes, but will the disco boxes fit or would I need to adjust mounts and get a shorter rear prop etc?

Not worth the agro a disco box is to long. If you want a lt77 then get a defender box.
