Didn't it come with instructions? I have installed Addco bars and Hellwig bars — both were more or less obvious id you laid out all the parts. Yes, they use the holes in the lip on the front edge of the K. The Addco one is more typical. An L-bracket bolts to the K. The sway bar bushing is trapped by a loop and a flat plate. The flat plate is bolted through the vertical arm of the L bracket. So the sway bar is located in front of the K, with the bushing loop facing forward. Does that make sense? The question is whether the L goes up or down — you will have to try it to see which way fits.
