According to some helpful folks here on this site it appears this is correct for basically any Camaro or Chevelle that uses a 772 fan. (396/427/etc.) It's got no date codes, so it works on about anything. The clutch is coded CH with the original ink stamp and overall the entire assembly is in nice shape and totally original.
195.00 plus shipping for the whole works. I'd separate the clutch and fan if you only need one part or the other.
