Pushed aerotank center pin too far now can't get it back in

[The Joel Train]

The title says it I was going to push out the center pin to fix the battery connection and like an idiot went too far. It completely came off it can only go in from the outside but the rubber stopper prevents that anyone ever fix this?

Well, the good news is that lots of stores online and B&M sell the replacement bases for them.

Thanks but I ended up fixing it I pulled the rubber stopper through with tweezers and pushed the pin in and good as used
