I have a couple of 69 Impala frames, and have a friend who needs a frame for his 64. I know my frame is good for 65-70 , but my interchange book does not go back to 64.
been covered previously... 65-66 frames are the same....67-70 frames are the same but different. the rear control arm crossmember is very different between 65/66 frames, compared to the 67-70 frames.
Best frame is 69-70; has bigger front hubs and is also more likely to have disc brakes, especially if you are luckly enough to score one from a 70 Impala Custom or Caprice on which discs were standard equipt.
