I understand that in some year not too long ago, there was an improvement made, that when the door is closed, the side screen goes into a slot at the end of the windscreen. this presumably is to cut down on draughts and perhaps rattles.

3 questions:
Was it a very effective improvement?
When was the improvement made?
On pre-improvement cars, can it be retrofitted?

I look forward to your knowledge and experience input.
