DartThis74 (Aaron) is my son and we finally worked this out on his Dart. The Hayden clutch did work perfectly on his 360 with the Champion radiator. We used the OEM five-blade fan and the hole spacing lined up exactly. There is approximately 3/4" clearance between fan and radiator. It was a pain in the posterior to get the bolts installed and tightened (very tight quarters). With this setup, the engine temp barely gets above the first tick mark on the gauge, and we still haven't come up with a solution for what to do about a shroud.
