Total Width needed for Aqueon 125g Dual Overflow

[CovingtonRK]

I've just ordered a125g Aqueon Megaflow tank (72" wide), and I'm planning to add a 3d background from UniversalRocks. Since my tank is 4-6 weeks out, I'm hoping someone can help me determine the overall width measurement of the back panel (including the additional width needed for the dual overflow boxes). I'd love to get my background delivered around the same time that the tank is delivered, so any help would be wonderful!

I'll measure mine over lunch break, if I can remember.

Edit: inside or outside dimensions?

Mine is 18 inches.

I'll ck the overflows. Mine is painted black which you might want to consider unless you're going to keep you back wall scraped of algae and coraline. I let the back wall fall to the whims of nature as it is too hard to get back there (I'm a short gal)
