No expert here, but I think it will better to do them together. You can drill and tap the air hole, as well as grind the D44 oil return slot without the pinion installed so cleaning will be easyer.
Also while the chunk is full of metal chips I would vent the chunk in the D44 and run a oil return tube from the axle tubes to the chunk to avoid pukeing oil out the breather but the choice is yours.
