Here is Joe Jump's bolt-on steering damper kit which he used to sell (not any more). In Joe's own words:
It really is a nice working damper set-up. I used to experience a low frequencywallowat speeds above 65 MPH (bags and a Harley-type windshield) - now that's gone. The damper is a hydraulic unit with seven adjustment positions from off to very stiff - a quality built Japanese unit. As you can see from themountedpicture, I've oriented the unit across the centerline of the frame so that the adjustment easily accomplished underway with a gloved left hand. In my case I've set it two clicks up from off and leave it there - don't even notice it in town.
