So its all done, actually last weekend it was complete. And to be honest it wasn't such a bad job after all. What made it more pleasant is that most of the time was spent nice and dry inside the car. I found some step by step guides on the internet which showed what nuts and bolts were where and the rest was obvious with some brute force as well. Now the wife and kids have a nice warm and condensation free windscreen ride to school every day. But not for long as the car is now up for sale, moving on to another project,a bit more practical for the school runs.
