I would question the VINs given here for the change. On the US cars
the suspension change you described somewhere around 85-d-900-545,
give or take 10 cars. I know of a later VIN car with the early suspension
which is the car Thompson Smith used to own. Again it's an example
of the current/published  documentation of these cars being incorrect.
