7 We've dropped our modified '90 radiator fan assembly in place. We used the '90 Corvette fans because the price was right. The only concern is the fans shroud requires modifying and clearance around the upper control arms. Dewitts has a set of fans that bolt right onto the Dewitts radiator, and they can install the fan package for you if you buy their complete package. This is a good idea for the Saturday afternoon warrior since the Dewitts radiator and fan assembly will drop right in place.
