Where can I buy these clips?

I'm cleaning up parts to put my engine back in the '69 GMC and there are 2 clips I need to replace. One of them goes on one of the clutch rods. The one shown is the the good one. The other one broke in half. I suppose I could just use a cotter pin but wondered if these clips are available somewhere. The other one I need goes in the clutch release lever. It goes in the hole in the lever where the bellhousing ball pivot goes. It basically keeps the lever attached to the ball.

Any ideas where I can get these items? I have no idea what they're actually called.
