MNE175AL-PLUS and a Morningstar Tristar MPPT 45

[jw6594]

I have a MNE175AL-PLUS and a Morningstar Tristar MPPT 45 attached to the right hand side.  I need a solution to cover the holes in the door that are designed for another charge controller type.  Is there a replacement door, a bolt on cover, or some sort of adapter to allow my charge controller to mount and cover all the holes? See the attached pic.

I used a sheet of lexan to 'cover' the holes in mine for safety...
