Check out my sweet Ebay score!! Anybody ever see these before??

Cool covers! I love vintage speed parts. They look like something Cal Custom would have made. My Demon GSs originally had C.C's on it when it was sold new. There were a couple different versions of the finned covers but those you have look just like one of them from memory. It would make sense too since I think Cal Custom was on the cheap side back then compared to M/T or Edelbrock stuff.
