Jonathan,
Sounds like you replaced both. Assuming you have them in, how have they been? My drivers side started giving problems after only 2000 miles and I live in Arizona and the car has never been driven in rain. I have the belt extended and clipped to stay out.
I go to the UK yearly to visit my wife's relatives so am thinking of taking both over and have Graham replace them. This seems a great solution.
Would you have his email address by any chance?
Many thanks.
