What are the steps for modifying the rear seat backward movement of the Terra?

[LeEmma]

The seats are fixed on top and can be directly drilled on the vehicle floor. The specific hole positions are based on your ideal seat location. Weld nuts at the drilled holes and refix the seats at the new position to achieve backward adjustment. Install sliding rails on the vehicle floor and connect the seats to the rails, thus enabling front and rear adjustment of the rear seats.
