jeep fan mount depth

I am redy to put an electric fan on my 69 so began researching past threads about which works best. i really like the jeep setup but never saw a depth measurement in those threads. i only have about 3.5" from my radiator to pump pulley bolts. also dont have a shroud yet. so, after all that, my questions are 1, will the jeep fan fit that, and 2, best place to find shroud. thanks in advance..
