The Ford seats come apart super easy. They just have plastic strips that snap over the metal or snap to themselves. You could probably change the seat covers in the whole truck in a few hours. If you use some baby powder, it makes them a lot easier to slide back over the seat foam.
I wonder how their leather really matches the stock stuff. My driver seat has a few cuts from the previous owner, but the rest are perfect. Ford wants close to a grand for new covers for just the driver's seat!!!
