05 Mustang GT Computer Code

Hello,

I know where to locate my computer code, but i'm not currently at my car right now. My question is this, does anybody know if the computer code is all the same in every 05 mustang GT???? If so, does anybody know what that code is and can tell me, I need that info.

Also, I need to know what the rear gear ration is, does anybody know that?

I would think these two things would be the same on all the 05 mustangs for stock, but I could be wrong. Sort of like all of us getting the same computer and someone asking whats the operating system, oh Windows XP.
