What am i doing worng my spitefire wont move?

It would help if you can provide as much detail information as possible in order to better assist you with the problem you are experiencing.
Year, make and model to start. Then, what are the problems/symptoms that you noticed?

I can't find any reference to any vehicle called a Spitefire, however Triumph did produce a Spitfire. I am going to assume that the engine starts and you can select gears. What often goes wrong with these vehicles is are the rubber doughnuts that give flexibility to the half shafts for suspension travel. Jack up the rear of the car and look for a completely torn one.
