Pusher Fan Clearance

Is anybody running a pusher fan on their 1967-1969 Dart? I am trying to figure out how much room there is between the grille and the front of the radiator. I would like to run a SPAL 16" Pusher. They have three different thickness, their thickest one pushes the most air. Can someone measure that space on their Dart for me? My grill is out getting rebuilt.

Thanks.
I pushed my front 15" elec fan out as far as possible so not to restrict airflow. it`s set to come on at 195, so far the 17" mech fan hasn`t needed any help, altho I don`t have any real run time on it. I do have a new 16" chrome elec fan for sale if ur interested. not enough room for it in my car.
