At the chassis point above the rear silencer mounting was changed. Up to that point the rear mounting consisted of two rubber bushes one either side of the exhaust clamp and then a bracket between the upper bush and the floor of the car.
After that point there was just one single rubber mounting between the clamp and the floor of the car.
