1994 Rear Brake Drum--HELP PLEASE!!!!

:frown: I have a 1994 Buick Skylark I was given when my mother passed away. I have never seen a brake drum without an opening to release the brake shoes. I can not get the rear brake drum off to replace the brake shoes. How does it come off? I can not afford a mechanic so I have to do all I can myself.

Just in case anyone else has this problem in the future.... I opened the bleeder to let the pressure off and still nothing.... I gently pried out on the edges of the hub and noticed it was not moving in the middle...I used a high quality silicon lubricant and sprayed it inside each lug area as I pried it out slightly...I repeated this about a half dozen times and slowly pried one area and then rotated the drum about an inch or so and pried again...after about 20 minutes it came off.... the hub was actually rusted to the spindle...
