Correctly reproduced 1953-1962 RH Tie Rod Ends are sold by which direction the thread goes. A right hand tie rod end has right hand threads, it is not which side of the car it goes on.
Note: These new design tie rod ends come pre-greased with (EP2 GREASE) and are now a sealed unit that does not require any additional grease, the Zerk fitting is for cosmetic purposes only.
