Hi Martin, if you are talking about just replacing the wiper rubbers, I think that you’ll find that these are of a fairly standard profile and you should be able to find a suitable replacement blade in Halfords or other car shop.
I replaced mine with (old) rubbers from windscreen wipers that I had taken off another car.
If you still have any remaining rubber blade, take it along to the auto shop and buy a new blade that matches the profile (try to buy just the rubber blade if you can).
Then just cut the new one to length – you’ll have to do a bit of bending of the relevant clips to remove the old rubber and fit the new one but its an easy job.
Don’t forget to refit the spring steel strips on each side of the blade.
Hope this helps,
