Hi I have a 535d MSport it has the step/auto transmission, it has had an upgrade to 330bhp now I want to fit the Paddle Shift system, I understand age is critical to get the correct parts does anyone know of where I can buy all the parts I need, I have the M Sport wheel with the round air bag and the car is a June 2005 build date, so if anyone can either supply me with the parts and a instruction sheet I would be grateful, I believe once done this is one of the best mods that can be added, CAN ANYONE HELP???????
