99 Grand Cherokee Fan blade swap?

Hey I want to swap out the stock fan blade, I was looking at a Blade like this one Moroso 64000 Moroso Stainless Steel Flex Fan
However I cant find one that is made for a 99 Grand Cherokee has anyone put one of these in? did you notice any improvement on mpg or horse power?

One last question, how hard was it to install and any installing tips would be greatly appreciated.

you will actually notice a loss in power over a working clutch fan setup not to mention the flex fans are loud. An electric fan might free up some power though, you can probably grab one from something with a similar sized radiator at the junkyard cheap.
