If you can't get it, you might want to try any quality HG flour with a 13-14.5% protien content....such as All Trumps HG Flour.
Pennmac.com is a great place to buy Ezzo Pepperoni, Grande Cheese, and Flour, in case you're interested. It was recommended to me on this website, by a fellow pizza maker.
What I like about them is...They sell two kinds Ezzo Pepperoni. They also sell the highly recommended Margherita Long Pepperoni A/C. One of the very successful Pizza places recently highlighted on the Travel Channel uses it.
I haven't tried the Margherita, but ordered it today and will give it a try.
