Hi, the link given earlier by Lanciak69 is a very good one. When we bought our Ulysse and started listing the things that needed attention, spinning locks was high on the list ( the novelty of guessing how long it would take to get in the car each morning was wearing off ). I posted a question as you have and Lanciak69 came to the rescue with the link to Maxyboy. No they are not cheap....but they do the job, and when fitted, give that fraction of a seconds silence before the wife:worship: finds something else wrong.
Happy motoring!
