toilet seat hinge pins?

[JohnGalt48]

On what appears to be the original toilet in my trailer, I've managed to lose the second of the two metal pins that hold the seat on. One was missing when I got the trailer, and I just "dealt with it", but now, after a 6,000 mile trip out West, the second is missing in action too. So now, the seat is on the floor....not good!
Does anyone know if these pins are available anywhere and what exactly they're called? I guess I could do some "backyard engineering" and modify some bolts or something to work but.....if the the real is available somewhere, that would make me feel better!
Thanks

Now I just gotta find somebody that stocks them.
