Transmission and gearbox changes also are included in the significant modification list as they often require moving cross members, changing the exhaust, changing the length of the driveshaft. Changes to the internals of the original transmission are not considered a major modification. Changing of the rear axle of the vehicle from the originally offered option is also considered a major modification. Any change of the rear wheel wells to accommodate a rear axle width change is not allowed and the installation of a final drive from a different vehicle type is considered a major modification. This is another time that an independent collector car inspection can help you determine if the vehicle has been modified or not.
The vehicle is also required to have the original steering, suspension, and rear suspension designs. There can not be any modification to the fabricated location of the spring hangers, A-Arm or Wishbone locations or modifying of the wheel hubs to accommodate suspension changes. Steering system changes from a steering gear box style to a rack-n-pinion setup is also frowned on and will get the vehicle stuck in customs leaving you with a heavy bill afterward. Modifications to the rear suspension can include changing of the springs and shocks however the system cannot be altered. In other words, the vehicle cannot have been changed from a leaf suspension system to that of a 4 or 5 link live axle system.
