RS 3 Shell removal

[plint]

I want to switch shells on 2 of my RS 3s.  One is DCC sound and the other is DCC.  How do the shells come off??  I don't see any screws and my paperwork doesn't explain it either. 
Thanks

I think there are several very tiny screws that hold the shell on actually if I am not mistaken.

Remover the 2 screws holding the couplers on. Remove the screw holding the fuel tank cover on. Remover 2 screws that hold body to frame.   Joe
