Found my dads original 1971 duster!

No, that's correct. The core of the rad is installed closer to the engine.

That fan is wrong as well. Probably out of an aspen or Diplomat or something.
Hmm. Ok thanks. They told me today that the core was way too far back. I’m not sure what else could explain my original clutch fan not fitting
Will it hurt to try this fan? Although I can’t fit the shroud, it looks very aggressive. I was love to get it running enough to keep my alignment appointment. But definitely not going to risk overheating
