Thanks everyone, I ended up picking up a whole spare coal tender off ebay. It wasn't great with the exchange and shipping but at least I have spare parts. In answer to another question, yeah this is only going to run at Christmas. Even with the cost of the spare the set worked out much cheaper than what I have seen the sets selling for online.

Hello. In 2019, I bought a new Bachmann Night Before Christmas set. Before I could use it, along came baby and I shelved it until this year. I recently opened the box and discovered the tender car has a broken rear truck. It can't be glued and won't run without derailing. Because of my own mistake in not checking it out before storing it, there's no warranty or exchange option. I'm having difficulty finding a replacement part as none of the trucks look the same as the one I'm replacing, even accounting for the parts that can be swapped on the truck. Can anyone point me in the right direction please?
