We bought a 1996 Oceanis 351 in the late fall and being doing minor repairs getting it ready for the spring. The gas strut and mounts for the refrigerator lid are missing and opening and keeping the lid open is a pain. Any one have the details on the lifting strut- length and force?? Beneteau USA acknowledges that a gas strut was used, but has no details or where to get one. There are a number of places on the web to buy the struts if you have the details. Help and thanks !!!!!
