Even fixed it will probably flex more then before and crack again; but at the end of the crack drill a hole (1/4" dia or so) [this will keep the crack from getting any longer] and then for the length of the crack drill holes on both sides of the crack. (Big enough to get a zip tie thru) about every 3/4-1" and use zip ties to hold together. It will work, probably for a long time if you don't run really high speeds. I have done it before on older sleds that for some reason liked to be track side up more then down.
