Hi Marius,
Sort of, apparently, they were not fitted as new, so my only option is to have them retrospectively fitted, but that is going to cost around £450.00, even if I buy the actual mechanism on eBay, so that's not likely as I am far too mean for that. there you, you live and learn. Best Wishes
Paul
Marius let me know what you decide or any outcome, if I change my mind, I will post an update.
