Removing Piston Pins

dart4forte said
I need to remove the pins out of some 273 pistons. What is the tools remove the clips. I had one but I can’t seem to find it. Probably loaned it out and never got it back.

It's been so long, I think they have circle clips and not snap rings. A o ring pick should do the job. Any pics? There are 3 or 4 different kinds.
