4211L x 2.  There are a few unusual variants on the standard XK140 / XK150 Inner tie rod and this is one type. This version is 1/2" longer and slightly different design.Shown  in the second picture compared to an unpainted 'standard' or commonest type. We have also seen male versions with outside threads, but have never seen these reproduced as the would require a different track rod end! But there are a few cars out there with them for whatever reasons! They are not as the Jaguar Parts book  illustration.

NOTE AGAIN THAT THESE ARE A SPECIAL DESIGN, BEFORE ORDERING!!
