This is an exploded view of your rear axle. It doesn't have "C" clips to hold the axles in like a 10, 12 bolt Chevy or Ford 8.8". The bearings are pressed onto the axles with a locking collar with a retaining plate sandwiched in between. Remove the 4 retaining nuts to pull out the axles. If they are stubborn hit it with some rust buster let it soak. If you can sneak 2 nuts in between the backing plate and retaining plate tighten them so it will keep the backing plate from coming off and messing up the brake line but it might be too tight. Then you can either put the drums on backwards with the other 3 nuts facing opposite (tapers out) and use the drum as a slide hammer. If that doesn't work use the puller attachment for a slide hammer shown below and it will come out whether it wants to or not! It might help to have the opposite tire on the ground if you don't have the car solid on stands as it could shift trying to get them out.
