Sold as a complete set that includes the two-piece seat and removable driver backrest. Mustang's seats feature a 16" wide deeply pocketed driver bucket that sits you at the ideal cruising angle. The entire 13" width of the comfortable rear seat is fully supported by Mustang's unique internal steel wings--no sagging on the edges, no more passenger complaints. Built on a marine-grade fiberglass baseplate, the two-piece seat mounts just like stock. Mustang's touring seat is available with or without a built-in driver backrest and is also sold with studs and conchos.
