Interesting. MPC says it is for "E-F-U100/350" and "Before 8/83". It is "Fawn-simulated leather". I'm sure it'll fit a pickup or Bronco, but have never seen one with a wheel other than black. However, the MPC goes on to say that a -B is "Medium blue-simulated leather" and is also for the E-F-U100/350.
