I have a prestolite valve body I'm trying to rebuild. From my research, there's a piston that needs an oring changed but can't figure how to get it out and trying not to break it. There was snap rings on both sides that I removed. Also not sure about the check valve balls since they fell out when I took it apart. Any help is very appreciated!

take it nobody knows?? Thinking about pressing it out but like I said, really don't want to damage it. Hard to find old parts like this..

Was able to get it apart.... Had to put it back together, plug where lines would go and blow with compressed air. Hopefully this helps someone in the future!!
