- If using the Triumph chassis the engine should be fitted using the original type mounting plates, putting the left hand one on the right hand side and vice versa. This puts the engine further back in the frame. If using the Burlington chassis, the engine must be fitted in the same position as it would be in the Triumph chassis it replaces.
- There are a number of options for spare wheel mounting at the rear, for further details contact the Class 7 Co-ordinator.
