Here is a 12Volt DC Delco brand air compressor to fit AMC Eagles and many other models, I would presume.  These compressors were employed for powering auto-ride suspension control.  Could be new old stock; but I am unsure, so listing it as used.  I connected a 12V battery to the unit, it purrs and pumps air perfectly.    Please check the photos and ask any questions you may have prior to placing your bid.  Free shipping in the continental USA!
