So I have a ship that didn't come with the little plastic center piece for the dial. Is there a way to get just one of those, or does anyone know where I could get some type of piece to make the dial work correctly?

Contact FFG customer service. They'll take care of it.

All of my core sets came with an extra one. Maybe yours did too.

Yeah, my core sets came with an extra one as well. and if you bought the Tantive than you can use one of the dials from the longer range ruler and then just fold up the ruler.

I've got an extra one I'd be willing to part with if you need it still. Just let me know.

I bought a HWK-290 that turned out to be missing that plastic piece. I contacted FFG customer support and within a week I had a replacement. No questions asked. Seriously, they're the best.
