I have a type 9 transmission with a VDO right angle drive and I want to use a Smiths speedometer that I have. I saw that caterham advertises a type 9 with the right angle drive that marries to the Smiths. Does anyone know if this works?

Nothing to stop it working, as long as you can get the correct cable. The Speedo will probably need callibrating though!
Speedy Cables will give you all the info you need.
