You don't need to weld it, its a press fit so it will stay where you put it.

The problem with the late 235 in an earlier truck is that the fan sits too low on the radiator for efficient air flow. I run a shortened water pump on my 261 but I run an electric fan and don't bother with a mechanical fan. It works fine and stays cool even in 100 degree heat, but it is a big fan.
