Hey peeps. So I am attempting to restore a MVS 2-Slot and I am having difficulty. I have two MVS 2-Slot PCB's and one had the Memory Card/Headphone Jack built into the board, another has a pin out that goes to an external Memory Card Reader/Headphone Jack.

Which 2-Slot PCB goes into my cabinet? I have tried pressing/lining up the 2-slot to match the cabinet and openings on the outside and no luck. I've searched online and every image I come across does not have the PCB pressed up at all.
