Austin 7 shaped problem

[@awalk5177]

I'm fascinated by these Trials cars, but it seems it is mainly a sport for the south of England. Where can I find information of the specifications to allow me to build one?

You might invest in some wheel dollies,

I would probably have to invest in a smooth floor to run them on first, unfortunately 😏 or can you get them with off road wheels
