Unfortunate, but kismat on your timing. I am on the hard now 70% through new strut replacement "surgery".  PM or email me and perhaps I can give you some insights as to what's up and photos of the entire process. While your strut is probably ok, start with this Catalina Direct attachment for reference, (factory drawing) of how it is installed, which should help with how to resecure it.
