I will try to use a clutch fan until it just doesnt fit. you dont look to have a lot of room there.

a clutch fan is deeper than a flex fan, but it will turn off when not needed, a flex fan is always cutting air.

if electric is all that will fit, most have enough shroud on them and dont need one that covers the whole rad. those will actually restrict airflow when the fan is off.

using a fan controller is better than a simple thermo switch, but a good thermo switch and relay is pretty reliable too. They sell an import upper neck fitting that has a spot for a switch if your intake doesnt have a spot.

I use curved blade generic fans when I cant use a clutch fan.
