Can I Replace The Top Steel Pin On My Hubs?

[Medium Dave]

Sorry if this makes no sense, but I was wondering if you can get a replacement pin to go in the top pivot of my front hubs, here is a piccy of a different hub, but the mark in red is where the appropriate steel pin goes ->

-Long story, but I am using them for my locost project and removed the pin to make up a bracket to connect a studded spherical bearing, as it turns out I wont be able to get the car engineered like that, so I need to replace the pins and use the standard swivel.

Much thanks in advance

aren't they cast/pressed in?
