sks sporter question

hello, i have a sks sporter. the sks's that hold the ak mags. not a conversion, but the one that come from the factory like this. i am trying to find a after market folding stock for it. ive been told by all dealers that they dont make them, but yes! they do. i have seen them and have pics, and they dont have to be altered. simply because they cant!. the mag well on the sporters are almost wider than the regular sks's stock. can anyone in the know, help me find one. thanks
