You are correct. I looked up the numbers on the blades and they say Ford. I will take it back. This guy has a 55 chevy, 53 chevy truck and a 65 chevy impala all in mint condition and all kinds of chevy parts. I thought he was selling me a chevy fan. Oh well he is here in town and I know where he lives. Thanks Bruce for your much appreciated help. On with my searching.
