Hopefully the pictures show how I made it. Just a bit of drilling and measuring here and there, didn't take long and cost around $25 (including $18 for the tripod mount I think). Aquarium tube around the U-bolts and duct tape around the rod protect the headrest bars from scratches.
As you can hear, it still needs work and I seriously hope I don't go sideways into a tree, I don't think that door stop would stop the rod penetrating my skull!!!
Besides the rattle, it seems to work very well. I would have thought that the picture might have been a little shakey with the camera mounted to the seat, but yours seems very steady indeed. Have you taken it over rough roads?
