If you have been following along with some of my YouTube builds, you will have seen I use this custom brass tube for some of the axles. I normally sell these tubes as a part of a larger kit, but I have  been asked if I'd sell it on its own.
 
So simply choose the car you want from the dropdown list and then the quantity. The list will grow as I do more builds on the channel.
 
If I've missed one, please let me know
