New old stock GM part# 3758538 (first/early part number) that also was 3771868 3830166 and 3872326.  Both are cast 3754166.  Chevrolet front brake drums.  Early part number show applications: 1959-62 passenger cars except metallic lining, later part numbers show for 1959-70 passenger cars except metallic linings and 1963-65 Corvette except metallic linings.  Probably for the 1965 Malibu Z16 too, but we could not find that in our parts books.  You know your car, so purchase based on your knowledge - no returns.  Found in an old Chevrolet dealership in original GM boxes.  Hard to find matching NOS pair.  PLEASE be sure this fits your needs - no returns.  We circle a couple very minor rust spots on the inside of one of them.  If you are familiar with these, you know these are about as nice as you will find anymore.  See photos. Sales tax may be applied by ebay for some states. Thanks!

NOTE:  Sold as-is - no warranty.  No returns.  Ship cost shown is for continental US 48 states.  Please be 100% sure this fits your needs.  Even though eBay is adding a video to every listing saying they promise items fit your vehicle, we do not accept returns and it is still your responsibility to be 100% sure this will work for you before you buy.  Thank you.
