Old Futaba Servo Horn

I had some old Futaba FP-S26 servos sitting around but no servo horns for them. I wanted to use them on a little robot project but couldn't until I had a way to mount the wheels to the servos.

Normally I'd go to my box but all my servo horns are for the round style shafts and not the old square drive shafts.
