66 Dart steering column ground

Hello everyone, I have a 66 dart Automatic floor shift. My horns are not working. I have traced the problem to a lack of ground in steering column. I tested all components, i.e. Signal switch, horn ring etc. I found that if I hook a jumper wire directly to the steering shaft my horns will sound when button is pushed. If I just ground to sterring column housing they will not. Does this model dart have an internal ground in steering column? Does anyone have a exploded view of this column that may show how ground is attached. Please advise. Thank you, Ed
