Fixing Colecovision Super Action Controllers

[SnapCraft]

I have some non-functioning buttons and I'd like to get in there.

 

I've searched everywhere on the net to find help to do this. After unscrewing the two bottom and two side screws, how do you take it apart???

 

I remember this same feeling when I tried to first take my Colecovision itself apart--a lot of brute force. Scary.

 

Any tips? Do you take the front sword-like shielding off first?

 

Thanks!
