shot doesn't tell me much, they could just be worn, chipped anything, since it worked. I have no way of knowing without asking, everyone's definition of "shot" means different things.
busted or broke, yea that tells me they are not able to be put back in the rear.
I've seen it before, split completely in two and then I've seen chipped or missing teeth, or even worn down badly. I wasn't sure exactly what "shot" meant, so my bad.
Now with no spiders c clips are only going to hold on by luck, the axle could walk in and cause the clip to come loose, continueing to move it can cause them to then walk out.
Honeslty I'd leave the center pin and bolt out, all the spiders, then just push it.
