A833 Gears OK or not

Here are some pics of a A833 I want to put into my car. I am going to rebuild it, but I am not sure if I need a couple new gears or if there is a way to recondition them. The trans supposedly came out of a running/driving car, but you never know. So let me know what you think . Pics are 2nd gear, 3rd gear, 4th gear.
