Electric fan install help.

I used 2" wide, 1/8" thick aluminum bar stock. I used the existing holes in the mount on my 26" Champion radiator and then drilled the holes for the fan shroud. You can see 3 of the bolt heads that hold the bar stock to the radiator, the 4th is underneath the top right fan mount. And of course the hardware holding the fan to the bar stock is easy to see. This is what mine looks like.
