Hey, the use of washers is a genuine fix (it even says so in the destructions) it was just my use of electrical ring connectors with the ends chopped off as washers (on the basis I had no washers that fitted) that was a
slight bodge sorry, deviation from correct install.
It worked didn't it?

Now thatmy garage is tidy and organised, it means that:
a) I can now find proper washers.
b) I have space to store the Rallye interior
