Where do these pins go? 742 SG case

So, I pulled the center section out of the 65 polara and out came 2 small pins. I honestly don't know where they go, but one fell out onto my chest
when I pulled the center section and the other was in the housing. They are small pins with a round head, maybe 3/8 inch or so and not threaded.. must be held in by gravity or something. I can't seem to find these parts when I'm looking at rebuild kits. Any ideas?
