Mercedes S123 estate - rear seat re-installation

Re-installation of the rear jumpseats in the 7 seat 123 wagon/estate/kombi. As my car undergoes restoration, I am changing the interior colour to black and sourced some black leather rear jump seats. It appears that most companies who make new leather/covers for our seats, dont make them for the rear jumpseats. This is the process of resinstalling them which wasn't overly complex looking back, but took about 4 hours or so. Remember to give your carpet a good clean prior to doing this as its out, its worth doing! I hope this saves you some time should you need to. I also see no reason one can't install jumpseats in a 5 seat 123 wagen if you have the parts from a donor car.
