Which mount for Red Sea 50 LED???

[BG107]

I have an IM 25, which is around 20 inches in total width, around 15 for the display. I believe that the dimensions for the Red sea 90 mount are better for my tank. Will the 50 LED fit in the 90 mount? And is this a good idea? Or should I just buy the 50 LED universal mount? Anyone have any experience with this? Thank you.
