rubber thing fell of my car, what is it?

[Randell]

the other day i backed my car up to work in the garage and this rotten rubber bit was on the ground where the car was standing... the number on it is 1133 671, i haven't been able to find anything using that number though.. does anyone know what it is? it seemed to come from the driver's side (RHD)
