Alternatives to kick stand retaining pin?

[Rivnut]

Has anyone come up with an alternative for a Schwinn built-in kick stand pin? I've lost a couple and figure there has to be a cheap solution for replacing them. What have you used?

Cut off the head on a US Steel 16d common nail and size the head to fit in the hole.

I have about 3 dozen that I have salvaged over the years, I could send you some to have on hand.

Gordon,
I sent you a PM.
