Adding a Rider Socket

So I was trying to make a mod to make the Eurypterid tameable and rideable. But I noticed that the eurypterid skeleton does not have a rider socket. But I have seen mods featuring other creatures that in vanilla ARK lack a rider socket, yet have scale your character to a proper size and position when ridden. So for the sake of everyone who wants to ride eurypterids, I must ask how one can add a rider socket to a skeleton that doesn’t have one.

(And while I’m at it, I suppose I might as well ask how I can make Eurypterids eat.)

Edit: Nevermind, I found out how to add the socket.

I know this is over a month old, but could you explain how you added a socket? I’m trying to do something similar right now and having trouble figuring it out.
