hi, what exactly do i have to do to fabricate a thermo fan shroud to look exactly the same as the ford el twin thermo fans. what i thought about doing was getting 2 identical single fans and mounting them on a bit of sheet metal or plastic and fafricate it to look exactly the same as ford el twin fans and would it then blow the same air as proper ford el twin fans if i got 2 identical single fans with a s blade and fabricated a shroud to look like el twin fans. the reason is im getting a ed fairmont sedan and doing thermo fans conversion and i want to know about fabricating shrouds with 2 fans.
