actually I have a lightweight "folding" stock. I bought for my sks a while back, but later refinished the original stock, and fell in love with it. So I am looking to sell the aftermarket one.

I have both pieces to make it either folding or fixed. (was an extra 9-10$ iirc)
I would let it go for 40$ plus shipping if someone wants it.
A word of warning though, you will need to keep it as a fixed stock unless your sks is old enough, or you have enough u.s. compliance parts on it. Otherwise you could be in violation of batf rules.
last but not least, my neighbor has one with the aftermarket scope and bolt cover combo. I haven't shot his yet, but he says very good things about it. For less than $40 I will have to try one myself.
