Hey Bob, my instructions from my superior kit show there were 2 styles of k-2, one had just 2 springs and the other had 3 springs and the other associated parts you were expecting. You most likely have the 2 spring train. My superior kit had me remove all that stuff anyway. Check out your instructions a bit better. I will send you a photo of mine and hilight what I am talking about if you need.

Edit. Just looked closer at your photos. Your photo with your superior kit instructions, the far right page. The top illustration, step 1-8. Go up to the K2 and see the arrow pointing down to the smaller box below? Thats what I am talking about.
