interchangeable cooling fans?

i have a 97 gt found a cooling fan out of a 96 v6 need to know if they are interchangable before i spend the money at the junk yard

I am 99% sure they are different. I know they dont mount the same as an assembly but I think they have different motors as well (poss diff rpm's). The motor itself may mount up to your assembly but I know diff part #s are listed .It may not cool properly.
