I just took two measurements that might help. I have a 1" spacer on my fan to get it centered in my shroud. 1/8" or so fan blade flange. 4 3/4" from flange to radiator. 3" from radiator to where it attachs to the support in line with the fan centerline (rad side supports are wider at the top). I have a big truck radiator which is 1" deeper than stock small truck ones.
