I would probably replace it, especially on a nice, symetrical rack that was missing that one tine to make it perfectly symetrical. That's just me though. My buddy has one where he fixed the tine. THe cool thing is ( I know this will sound weird) is that he did a bad job on it, so you can tell what it would look like with the tine but it's not like he's trying to cover it up and make you think it is really there.
