I could be wrong but IIRC, the cradle won't fit in a cabinet that has the "flap" on the right side of the opening, it has to be a cabinet that has the opening for a 401/500 series and up, with the straight across front opening, and RotaryQueen is right, it has to have those front clips. The cradle attaches to the hinge pins just like a machine does.
