Well, an AMC 327 distributors may have changed, but during those years they still used Delco distributors in the cars ( '64-'66 give or take ).. Rockauto lists A1 Cardone #301880 as being available and a little over $40. I just used '66 Ambassador.. The Delco distributor will make it run and take off the shelf points and cap. You could use a Chevy V8 Pertronix kit if you wanted, but same kit would have an AMC list as part fitting... Not sure if AMC ever used a Motocraft ignition in those engines. They used Motocraft distributors in the 6's for a couple years in California cars IIRC, but not sure about the V8's
