The problem im having is I dont want to change the mount its a tenon mount. I can make a clip but I"m not sure how I can make a spring.Ii only have about 5/8 of an inch between the pivot plates to fit a spring in. So I am kinda at a loss right now. If I had an idea what the spring was like on it and how it fastened to the post before I might be able to come up with something but no luck so far.
