Marlin 70 folding stock-help!

[spartanpride]

I just ordered this stock http://www.e-gunparts.com/DisplayAd.asp?chrProductSKU=885350A&chrSuperSKU=885350&MC=&CatID=4066&mySort=2 for my Marlin 70 from Numrich. It is very ugly, but it looks like it used to fold (even tho it says "Non Folding") because it has a hinge type thing and it wiggles a bit there. I couldn't resist for 15$, but does anyone have experience with it, or how to enable it to fold again?
Thanks
