(1966) Horn Ring w/cable part 8-33-121

Almost finished with my steering wheel project. I still have a stubborn gear selector to go as well as my horn. On the underside of the Steering wheel is the copper contact ring with the terminal. My terminal broke off. The part is almost impossible to find so has anyone soldered a male terminal onto the copper ring? Is this the best fix? I've attached a photo to clarify what I am talking about. Early A Steering Wheel R&I 14-9.jpg
