To protect the starter solenoid and engine wiring on Corvette Mark IV engines from excessive manifold heat, the subject shield has been released and will be in production approximately 3-28-68. In addition, the starter motor solenoid end cap will be replaced by an identical part except its material will withstand 4000F. For part identification, it will be colored brown instead of black.
A similar shield is also released for passenger Mark IV engines, however, due to lead time it will be come effective on 1969 models. A peculiar shield for passenger is required because of different exhaust manifolds.
