Corbeau Universal Seat Brackets are for vehicles with flat floor pans.You will be required in most cases to drill your own mounting holes in the floor board of the vehicle. This bracket is adjustable from 4-7 inches in height. Corbeau Universal seat brackets are powder coated in a black wrinkled finish and come standard with single locking sliders. Single locking sliders have a handle on the locking side that you pull to the side to slide your seat forward and back. You can upgrade to a double locking slider for an additional fee. Double locking sliders have a bar that connects the two locking sliders and you pull up on this bar to slide your seat forward and back. If you do high stress driving of any kind we recommend a double locking slider.
