With an Hitachi Twin Carb (GX-style) engine a RHD car there is clearance aplenty to fit air cleaners. But on a LHD car fitting an air cleaner it a bit tricky because the brake and clutch cylinders are on the left side. But the Twin Hitachis are more easily fitted to LHD 1200 than a twin-Weber setup.
