for what it's worth....
here is a conductor plate, electrical connector and solenoid spring replacement compliments of G-AMG over at the W210 forum

I'm sure there are others out there, bit the pictures (and simplicity) impressed me.....and his little SD package, which I'm not sure would cut it on a Chrysler platform SRT-6.

BTW - I have an SLK230 with a 722.6 stuck in limp mode - Carsoft tells me it's the rear wheel speed sensor. Hopefully that's all it is and not the TCM or something else.
Although I've bee nunder there and checked out the wiring....not much to see as it tucks up and o ver the wheel arch.....I havent been able to work out how to get into the cavity where the sensor detects the passing speed tabs....TIA
