Hacking EZ Flash Shell Replacment

[dinofan01]

I'm going to get a EZ Flash 3 in 1 for my DS lite. Ive also been thinking about getting a GBA micro just to have. The problem is though that the EZ Flash 3 in 1 is too small to fit in a standard GBA slot. Does anyone know where to find replacement shells so I can go from lite to phat and where to find them? I also found these M3 cases could I just put my EZ Flash in one of those and would it work?
