67 dart fan ??

The numbers are placed on a lower inside corner Steve. You would need to remove the shoud to read it. Referencing the bolt hole spacing on the radiator might be a better approach but... The slant 6 shroud will have the same bolt hole measurements and its opening offset left to right exactly opposite the V8 shroud. In some case the slant 6 shroud will work with a V8 when installed upside down. Again the bolt hole spacing comes into play.
