Super Gameboy (SNES / SFC) and SuperGameboy 2 Physical Characteristics

[Seymor Onion]

I own a USA SNES Super GameBoy.

I was wondering if the physical outer dimensions of the SFC Version of the Super Gameboy and Super Gameboy 2 were identical to each other;
Height, Width & Thickness at the thickest part.
I know they are different from the US Version.

I need to pick up one, or both, of the SFC Super Gameboys later today, and was wondering if I need to get both, or only one.
I only need it for testing/fitting purposes in my Game Case Design.
I'm not concerned with their compatibility with GameBoy Games.

The Japanese SGB and SGB2 are practically the same externally apart from the shell color and the link cable port on the SGB2.

Thanks for the info.
I'll try and get the SGB2, so I can be sure not to place any locking tabs near the link port.
