Dang... I'm close by, but have the weakest wire-cutters ever. If all else fails you can bring it to On the Route at Lawrence & Lincoln. They're pretty nice, I bet they could cut it down for you.
I am not too far from there and have Park cutters, which work well. Also out this way (W of you maybe 12-14 blocks) is Iron Cycles, a very nice and helpful shop. : )
