I am most certain that if you will remove the rear axle shaft you will have plenty of room to remove/replace the studs. To do this you will need to remove the wheel, brake drum and then move to the back of the brake backing plate and you will find six bolts that hold the hub and hub bearing housing to the solid axle housing. These bolts have keepers on them to secure them in place. You will need to open the keepers to allow the bolts to be removed. Once the six bolts are out the axle shaft can be pulled straight out. You should be able to work with this assembly to change the studs without removing anything else from the axle shaft.
The front wheels you will need to remove the cotter key and center nut to remove the hub. It is best to have a repair manual for the car to be sure you are following the steps and safety items correctly.
Good luck.
