[CA] Trouble finding replacement for C80 MFD

I am trying to replace my C80 MFD and the eS97 9" was recommended to me as a replacement. Upon closer inspection, it appears that the cutout height for the C80 is larger than the overall height of the eS97 9" and no mounting plate is available. I want to use my existing 600W transducer so the eS97 would be an ideal fit for me. I don't have room for a 12" display.

1) is there a mounting plate option for replacing the C80 with a es97 9" that I am not seeing?

2) Assuming that ship has sailed, is there another Raymarine 9" MFD that: (1) I can use my existing 600W transducer with and (2) will fit the C80 cutout (7.53"H x10.4"W) either out of the box or with an available mounting plate?

Thanks,

Dave
