bjr,
The ones I use have male dimples on the sides. They fit into recessed dimples on the shank and you tap them into the dimples. Look closely at the teeth in this picture and you can see the dimple on the side of the teeth. (sorry, no close up)
3RRL, Did you make that tooth bar? I have the same tractor with a Koyker 195 loader and I am interested in which shank and tooth you purchased and where you purchased them.
Thanks
