I have looked at the tie rod and drag link and see that the end caps in some cases are not flush with the rod. Some appear to be in too far. The Model A Service and Maintenance Guide recommends that the end caps be screwed in to compress the springs 25%. How do you verify that? After the end cap contacts the ball cap does anyone know how many turns the end cap has to go to compress the spring 25%? Thanks for your help. Ed
