I've got 4 new (to me- from genII cars) door strikers (two drivers/two passenger) for a w126 with excellent tongues, and four tongues with the rubber insert from the same- and there are more if I have lots of requests. The tongue can be used in the w123 or w126. There are two versions of the rubber insert, and two versions of the tongue (yellow and black) but both versions of the tongue are exactly the same shape and can be used on the drivers or passenger side of the car. The strikers are side specific. PM with interest.
