How do I get access to the inside of the dryer to replace belt

The sides and back are all one unit with only a small inspection panel on the lower right side in the back. It appears the top may come off but I can find no screws, and the smae goes for the front. I need help.

Could find no info on listed Model Number but this may help

At the front top, about an inch and a half in from each corner, are spring clips. Depress these clips with a putty knife, or similar flat item, as you apply upward pressure on the corresponding corner, and the top will tilt up and away to expose the screws holding the front of the cabinet to the sides. Before removing the front panel, unplug the machine. There’s electric current going through the door switch.
