Ah well that makes things more difficult. I found cockpit photos of 4 different J models but they must all be MH and not AH. I'm focused on an early J model, and after looking at walkaround pics of an AH-6J I saw the photo below. The red object looks like its a toggle switch cover and must be that AMS panel you're talking about. It looks like its in the place of the TACAN panel as shown below. Did the AH version not have the TACAN? What about the Argus 7000? It's a blurry pic but kinda looks more like a standard HSI in the spot of the Argus 7000.
