Looking good so far! Although it does look like the drum is not seated all the way down. The space between drum/hub should be much less than what you show. Torque it all down and see where you are at.
Also, I would recommend swapping out those brake shoes. Even though they visually look good, a new set will grab much better. There are new varieties available from multiple Brands that are FAR superior to the 60 year old shoes you've got there. Never cheap out on the brakes. IMHO.
Keep up the good work!
