I used their bunny ears. Note, the one I got had two screw holes not one like the US Graflex bunny ear, which only has one hole. I used one 8-32 flat screw, I had to bore out the bunny ear hole to fit it. Then used liquid nail to attach the piece to strengthen the connection. Works great and is very solid and was still able to use the a 8-32 retention screw. Pics below of my custom Prophecy with bunny ears.
