Thats a great find, i'm jealous that you have a glass shop across the street.
I'd have it cut to 28" tall (cutting out the chipped corner), and let them toss the rest of it. Remember that you can make your plywood box a little bigger than your glass, if you had 6" of ply on either side of the glass you could have an 8' tank (much less cutting), 4' front to back and 28" high, which would truely be a monster 96x48x28 = 558 us gallons.
I wish I had a spot for that!
