Room for a Clutch-Fan in a '65?

the answer is: probably not. on my 64 dart when i went to a griffin rad from the stocker i had to switch back to a mechanically driven fan because there was zero-point-zero room. however, at the time hayden didn't offer the shorty clutch.

i also had switched previously to the 70+ style stuff, so the snout of the waterpump may have been longer-- but that all worked with the stock rad.

it appears that you already have the cast iron pump so that is probably the shortest snout (and your pulleys are all lined up!) so i'd measure it off and see where you're at. you might run into an issue that the clutch ***'y may not take a smaller diameter fan-- most of them are in the 17, 18 & 19" range-- and that could interfere with the upper rad hose if it's center of the tank.
