A drive link assembly includes a case having a spherically formed inner ring. A clevis is affixed to a surface of the case such that is disposed horizontally between a first end and a second end of the clevis. A spacer having a spherical inset portion is positioned on the surface horizontally between the clevis and the spherically formed inner ring, such that the spherical inset portion is aligned with the spherically formed inner ring. A spherical bearing is seated within the spherically formed inner ring. A rod is affixed to an outer surface of the spherical bearing.

1. A drive link assembly comprising: a case having a spherically formed inner ring section;a clevis affixed to the case such that the spherically formed inner ring section is disposed horizontally between a first end and a second end of the clevis;a spherical bearing seated within the spherically formed inner ring section;a first spacer positioned horizontally between the first end of the clevis and the spherical bearing, wherein an inset portion of the first spacer is adjacent the spherical bearing and comprises a first sloped surface extending away from the spherical bearing;a second spacer positioned horizontally between the second end of the clevis and the spherical bearing, wherein an inset portion of the second spacer is adjacent the spherical bearing and comprises a second sloped surface extending away from the spherical bearing; anda rod having a rod first end, the rod first end being integral with an outer surface of the case, wherein an axial thickness of the spherically formed inner ring section is less than an diameter of the rod. 2. The drive link assembly of claim 1, wherein the spherically formed inner ring section is characterized by an open bore. 3. The drive link assembly of claim 1, wherein an outer diameter of the spherical bearing is less than an inner diameter of the spherically formed inner ring section. 4. The drive link assembly of claim 1, wherein the first spacer and the second spacer comprise at least one of metal, ceramic, mineral, glass, or plastic. 5. The drive link assembly of claim 1, wherein the first spacer and the second spacer reduce a range of motion for the spherical bearing. 6. The drive link assembly of claim 1, wherein the rod further comprises a rod second end. 7. The drive link assembly of claim 6, wherein the rod second end is attached to an articulated nozzle for a gas turbine engine. 8. The drive link assembly of claim 1, wherein a size and shape of the first spacer and the second spacer is modified based on a desired range of motion. 9. A method of manufacturing a drive link comprising forming a case having a spherically formed inner ring section;affixing a clevis to the case such that the spherically formed inner ring section is disposed horizontally between a first end and a second end of the clevis;inserting a spherical bearing within the spherically formed inner ring section;positioning a first spacer horizontally between the first end of the clevis and the spherical bearing such that a sloped surface of an inset portion of the first spacer extends away from the spherical bearing;positioning a second spacer horizontally between the second end of the clevis and the spherical bearing such that a sloped surface of an inset portion of the second spacer extends away from the spherical bearing; andforming a rod extending from an outer surface of the case, wherein a rod first end is integral with the outer surface of the case, and wherein an axial thickness of the spherically formed inner ring section is less than a diameter of the rod. 10. The method of claim 9, wherein the spherically formed inner ring section is characterized by an open bore. 11. The method of claim 9, wherein an outer diameter of the spherical bearing is less than a diameter of the spherically formed inner ring section. 12. The method of claim 9, wherein the first spacer and the second spacer comprise at least one of metal, ceramic, mineral, glass, or plastic. 13. The method of claim 9, wherein the first spacer and the second spacer reduce bending-based stress. 14. The method of claim 9, wherein a size and shape of the first spacer and second spacer are modified based on a desired range of motion. 15. The method of claim 9, wherein the first spacer and the second spacer include a first spherical inset portion and a second spherical inset portion. 16. The method of claim 9, further comprising attaching a rod second end of the rod to an articulated nozzle. 17. A method for installing a drive link to a nozzle assembly comprising: attaching a rod first end of a rod to an actuator;attaching a rod second end of the rod to an outer surface of a case having a spherically formed inner ring section, wherein the rod second end is integral with the outer surface of the case, and wherein an axial thickness of the spherically formed inner ring section is less than a diameter of the rod;seating a spherical bearing within the spherically formed inner ring section, wherein the spherically formed inner ring is disposed between a first end and a second end of a clevis;positioning a first spacer between the first end of the clevis and the spherical bearing; andpositioning a second spacer the second end of the clevis and the spherical bearing. 18. The method of claim 17, wherein the spherically formed inner ring section is characterized by an open bore. 19. The method of claim 17, wherein an outer diameter of the spherical bearing is less than a diameter of the spherically formed inner ring section. 20. The method of claim 17, wherein a first sloped surface of an inset portion of the first spacer extends away from the spherical bearing, and wherein a second sloped surface of an inset portion of the second spacer extend away from the spherical bearing.
