I have a 70 wood GTX steering wheel . The snap ring on the bottom that goes around the center spline shaft and holds down a copper contact that touches a contact in the column for the horn is always grounded . What breaks this ground. The copper ring has a rubber gasket to keep it from touching the wheel but when you add the snap ring it grounds the whole assembly. I got to be missing something that stops the snap ring from prematurely grounding the copper ring and not letting the horn switch make the ground. Thanks
