I am building up a Look 695, 3k, special edition frame. I am having difficulty getting the cable stops reinstalled. Following the directions from Look, (place the cable stop in its place on the frame and tightening the screw until the lip is on the inside of the frame), I cannot get the lip to go inside the frame. Obviously, I do not want to force anything. If any one has experience with these things, I would be most appreciative.
