In my 1 ton with the 235, stock radiator, and short water pump shaft the only fan I could find to fit is the original 216 fan, and even then it just fit, almost hit the crank pulley and hardly enough room to change the belt on the front. Had a fan break on a road trip, took a few hours to track down a replacement again, all I could find to fit was another 216 fan.
If I ever need a new water pump I'll use a water pump adapter plate which is a better deal all the way around.
You should look into the adapter.
