Wrong. The '13 EST Cartels can't have the same baseplate as the Malavita... EST Malavitas have the hinge, and '13 EST Cartels (restricted or otherwise) do not.
Early release 2014 EST Cartels do have the hinge. I just bought a pair to try:
2014 Burton Cartels
Maybe the non-EST ones share baseplates, but the OP asked about EST.
