Magnum Mech Fan in 73 A Body?

I need some help in determining if the factory mechanical fan will clear.
I'm swapping a 5.9 Magnum into a 73 Dart Swinger - original /6 vehicle.
I'm using a factory 73 spool mount V8 K-frame with factory 360 mounts.

1. Does anyone know if the factory magnum mechanical fan will have enough clearance to the radiator and will it fit in the same position in the shroud?
2. Or.. Can someone measure the distance from the block to the end of the fan assy from a factory LA V8 in a late A-body (as I measured in the picture)
