I learned something new today. I have a LHD car and I noticed that my clutch pedal return spring was missing, so I ordered one. When I went to install it, I realized that there is no bracket attached to the clutch pedal, like the RHD cars, and so there is no way to attach a clutch pedal return spring to LHD pedal boxes. I think the reason for this is the space between the clutch pedal arm and the steering rack is too close to allow for the spring. So, in short, RHD cars have clutch pedal return springs and LHD do not. I am not sure if this changed with the post 2005 pedal boxes when the pedal box was slightly revised (and probably made in China).
