How much of a difference is there between a new rear gear and a used one with wear like a 64 on dirt oval track box stock predator.

You shouldn't have any problem with "good" used ones. And of course it depends on where the wear is. On the sides, on the edges of the teeth or on the base circle. Pretty much have to look at them and you decide. I would only worry if they were real bad.
