When you say 'lynch pins' are you talking about the pin that goes through the clevis and has a circular spring loaded loop on the end that flips over to hold it in place? If so that is the style that I have and lost one. Now I just loop that little stretch cord with the ball through the loop and then around the whole connection and snap the ball into the loop to hold it all in place. I am making it sound more complicated than it really it. BUT, like you Stephen, I still check those clevis pin connections at every stop.
