I attach some instructions if you want to do a DIY repair (which works well at our boat for three or four years now). The broken springs are fairly cheap and available on Ebay and certainly other places. To replace the whole insert seems a bit overdone. One instruction is in German, but the guy who wrote it (also member of this forum) included a lot of photos which should guide you through the repair process. More important, he included the measuremants of the springs you should look for. Hope this helps and - if so - please say thank you to SY Confidence (I do not know his user name in this forum).
