Plow Mount for Sportsman 500 w/ Demand Drive?

New to the Forums, and any help would be greatly appreciated. I recently "inherited" a nice 2005 Sportsman 500 HO with Demand Drive 4×4. I live in the Mountains of Colorado and would like to install a plow, but I’m getting buggered trying to find a plow mount system that is listed as working with machines having the demand drive differential. Any of you fine gents (or ladies) have knowledge of a mount/system that would fit the bill? (Would prefer a front mount system but beggars aren’t picky.) Thanks!
