Where did I put my shift indicator...

Yeah, that's right. There isn't one. 67 Dart, column shift, anybody have pics? The only thing other than regular maintenance done to this car was a (probably dealer) install of a trailer hitch. I really don't know what could have happened to it. I thought it would be obvious once I got the steering wheel off, but it's not...I don't see a pointer or anyplace one would go.

What am I missing here?!
