Weather solid/flex or clutch what and why? Remember this is about mech. fans not electric. Im asking because I was going through a pile of fans as I need one and ive had one in the nos parts room I thought I was gonna end up selling since I didnt think it was ok for me but I never really looked until today. Mopar says its good for 15hp over the old type but to me it sorta just looks like a bit more modern 80s fan.?????? I paid less the $100 long long ago but have seen them for 2x that.
