This is additional information that I did not include in my review. Plunger does not fit in mounting holes. I had to change the clamp to make it work at all. When the mounting holes are opened from 0.250 to 0.281, the piston can move almost exactly over the mounting holes. I threaded a 20" bar into the clamp and supported it 18" from the clamp on the same centerline as the mounting holes. The clamp throws the bar out of the way about 3/4" and engages the clamp. I recommend to spend a few euros more for a quality clip.
