I ended up with a 19" fan with the 2747. I formed my own shroud, because the fan's front edge is about one inch from the radiator. It's always been that way, but other trucks have more space. I was having problems running hot, and the fan didn't couple with the shroud. You could probably get away with filing a tiny bit off of each of the tabs on the fan blade. A little bit would be all it took, and won't affect the balance, being that close to the hub.
