You'll need to match the dimensions and material properties to the existing one from the fork. As many have mentioned, that fork really isn't worth fixing and you'll be better served going with a replacement fork altogether. Note there could be other incidental upgrades required such as going with a threadless headset, and switching to v-brakes unless you find a replacement fork with a canti hanger.
