Yamaha Montage 7 motherboard

I’m looking for the Yamaha Montage 7 main board. You only have listed the montage 8 main board, are they different ones? If so, is there a way to buy the montage 7 board?

I just researched this, and it is the same board for the Montage 6, 7, and 8 - I updated our site to reflect this. Thanks!
