Your fingers are too short... If you see the available tools, they go up from the pivot point, then come down on the retainer. If you have $12 or so, go buy or rent the KD on the car spring compressor. If you cant afford it, cut off the "C", make an extension out and up, and then re-attach the C to it. The further out you go from the center of the pivot, the more "down" rather than "out" the tool will go when you rotate it on the pivot.
