A method of assembling a thrust reverser assembly for use in an aircraft gas turbine propulsion system. The method includes coupling a translating cowl to a fixed cowling, such that the translating cowl at least partially covers an engine, and is movable between an open position and a closed position. A rod end assembly is coupled to the translating cowl and an actuator is coupled to the rod end assembly, such that the actuator is movable between a first position and a second position. A torque bracket is coupled to the rod end assembly. The torque bracket includes at least two arms that each extend outward from the rod end assembly, such that a bending loading induced to the rod end assembly is induced to the translating cowl by the torque bracket.
