Can anyone please tell me how part #: 6705089 LIFT ARM STOP Was 6700615 is mounted on the lift arm? I was able to find a used part of it but can't figure out how it mounts on the lift arm. The hydraulic lines are on the bottom of the lift arm and it tucks against those but I don't see what holds it in place while it's not being used.
