Ah, I've had a customer come in one day with this same thing. What we did is recommend that they take the 23-126 pivot and use the 21-100 as a cap. Carefully compare this hardware to your own and let me know if that could work for you, as well.

instead of using the spring loaded bolt would the pin cap fit on the threaded bolt # 23-127
