speedometer cable, new in unopened package, I bought it but never found time to install it until I sold my car :-) this one has the part number 123-542-82-07 and I bought it online from ******** Arizona for a 1985 Mercedes 300D Turbodiesel (California car), but it might fit many other versions of the W123 series. Made in Germany. I paid between 40 and 50 bucks. Its yours for $ 10 (plus shipping). Shipping should not exceed around 8 bucks for a USPS parcel. I will let you know exactly if you are interested.
