Hi S-Class, I have thought long and hard about your suggestionto make up a steel plate and transfer all fittings to that plate. Unfortunately, in this lovely OZ country of ours, labour charges would render your suggestion at the expensive end of the scale and chances are that you'd finish up with numbers on the shelf that may take some time to move and tie up your money. SA may be different - labour costs appear to be much lower.
Anyway, I have managed to get hold of a new after market replacement unit - as previously indicated. This is what it looks like - made in Italy.....

As can be seen, a new motor is included and the whole box and dice is about 1/3rd the price of a genuine regulator that you buy from MB WITHOUT the motor. Regards Styria
Really, when you have a closer look, it is just that more simple than the Benz unit. Plus, it just goes straight up and down basically in alignment with the position of the motor - it's got to be more efficient and reliable.
