So now that I'm getting ready (soon :) ) to fit new pistons in my old Skoda Estelle engine, I found that the piston rods have "wire" C clips. I mean, they look like a piece of wire, no "eyes" or tabs with holes in which we normally put the pliers to squeeze the clip. Just like a C section of a spring. How can be those clips extracted? I guess using a needle-like screwdriver? I have seen this for instance, in power steering pumps, but much larger.
