You have the "Body" the black part screwed to the Fender and then the "Mounting Ring" (silver dish part) screwed to the Body, that's the problem. The Mounting Ring is supported off of the Body with the two adjusting screws, not screwed tight to the Body. The Adjusting Screws are located at 12 and 9 o-clock and the spring is at 5 o-clock. The screw slots in the Mounting Ring (silver dish) get inserted into the groove on the head of the adjusting screws.
Hope this helps,
