EMD F7A Shell Removal

[n6vc]

I need to remove the shell on a new Bachmann EMD F7A so I can install decoder. Can anyone help. I have tried spreading the sides to clear the tabs, but the frame doesn't move from inside the shell.
Thanks for any help.

Fuel tank snaps off then remove the screws. I believe there is four.

If it is like the new "Blue Box" models, there will be 4 screws around the fuel tank going through the frame that need to come out to release the shell.  If the one you have is like this, the 2 screws you see in the fuel tank, hold the motor cradle to the frame and don't need to come out unless you want to remove the motor too.
