I have a '78 L82 and the AIR Pump is factory, # 7817872, but the backing plate (or spacer) is Chevy Blue, the book calls for it to be Gray or Zinc. I wonder if Blue is correct because this is a very early car, built Oct. '77. Some things change after a few months of production. Is Blue correct or did someone paint it?
