Seat Adapters by Planted Technology. The Planted BMW E36 Seat Adapter is used to adapt the original BMW E36 seats to the Planted Seat Bracket. Like most Original Equipment Manufacturer (OEM) seats, the E36 seats do not have a universal aftermarket mounting bolt pattern. The Planted BMW E36 Seat Adapter will bolt between the E36 seat sliders and Planted Seat Bracket, allowing them to mate together. Originally developed for the Toyota Landcruiser, the adapter will work with any of the Planted Seat Brackets, although modification or removal of any seat belt tab(s) on the Planted Seat Bracket may be required to make room. Please also keep in mind that the BMW E36 seats may not fit in every vehicle. The adapter is made from 3/16 inch steel and is finished in a durable powdercoat. Hardware is sold separately.
