We set of Saturday just after lunch, taking a sample with us, just in case but only to find out that they were not open Saturday afternoons! Ah well - best laid plans and all that!
We tried again Monday morning and they were open and the parts were in - only they were the wrong ones!
After giving them the more detailed information for the car, we identified and ordered the right parts. They would have them just after lunch which meant another trip back to Chatellerault as we had a lunch date with friend back in Mairé (20km). Now, because they were getting them so quickly we wondered if they were just getting them from another place locally...so we found and tried another supplier but only to be told it would be next day - with our lunch time approaching we had to give up our search.
After another good lunch in Mairé we returned with a great sense of deja vu and at last picked up the correct parts.
