How do I remove an old acrylic neo-angle shower (3 piece)?

[Sherri B.]

I have taken the top bracket off, which allowed for the door removal. I have removed 2 small screws on each of the 2 panels that mate up to the bracket that is screwed to the wall...I took pictures from the top so I could see the channels and what I had to do to release the panels from the wall. I can not tell what I need to do from the top. I am unable to free the panels from the walls even though I have run a putty knife between the panels and the wall after I removed all the caulk. I also did the same to the top of the base unit and the bottom of the walls and the walls will move rather easily if I lean against them.

The problem: I can't for the life of me figure out how to get the panels to come off the brackets that are screwed into the wall.

FYI I would just break them (would give me great pleasure) but not sure if the husband wants to keep them for anything. I can't ask him because this is a surprise for him!

Thank you for allowing me to post and hoping someone can help me!

The panels are either riveted or screwed to the wall channels. Remove them and there will be three screws through the channels into the wall.
