    Those pins are generally tapered, and tapped into the hole. You can drill out the old hole, and put a new pin in it. Tap it in snugly and you should be good. A little red LocTite might give it a little more staying power.

    Ditto the above.

    If you have a staking set, you can tap the old pin out, usually easily. Tap it out back the way it went in because sometimes the end of the pin is peened a little, flush to the wheel. Trying to tap it through, instead of back, may make the hole larger than is necessary. Once the new pin is in the wheel, if you do have a staking set, you can gently rivet the brass around the pin with a staking punch.
    Clock tapered pins make good replacements but you will need to shorten it no doubt. If you use cutters to cut it to length, tidy up the end of the pin so no rough edges move along the warning pin indent on the lifting piece.

    To add slightly, I score the new pin by putting it into a pin vise and rotating it between a piece of 150 sandpaper. When you tap it into place it will bite with just a couple of very light taps with a 2 ounce hammer. To much force can split or deform the wheel. Those tapered pins can exert a lot of outward force.
