Basically you're swapping the entire drivetrain. The stock axles would work, but you'd need to gear them properly, and the D35 isn't worth wasting money on unless stuff was given to you for free.
Add to this ALOT of time, new exhaust, Driveshafts (unless you are VERY lucky), cooling system along with the hoses to connect it to the engine, Fuel delivery system, Engine mounting hardware including adapters, More time, fluids............
and alot of patience...
