I decided on a reproduction 7 blade clutch fan and factory shroud #325 I bought from Mancini's. There is a gap between the shroud and radiator is it necessary to fill it in? Still has to be better than no shroud at all.
I hate how aftermarket aluminum radiators space out the shroud like that so there's a fat gap. It's almost like they make the mounting brackets so wide in order to fit the rivnuts for the shroud mount. I ended up filling mine with a strip of aluminum. I figured what's the point of having a shroud if it's not close to the radiator tanks.
