I have 1238682514, 2614, 2714, 2814. I think there are two styles - one that has a deeper base than the other. But I'm not sure, I know left and right are different part numbers. Not sure if front and rear are different part numbers.

I'll loan you one. Contact me. I have a part that I would really like to have made but don't know how. The plastic cap that covers the screw on a Nackenrolle headrest from a W110/W111/W112 era...
