What size is the fan opening on these? I assume the "22 inch" refers to the width of the rad? In an effort to cool the car a little better I put a later, smaller sized, factory 7-blade fan & clutch on it and I'm hoping it will work with the shroud. I helped overall but it still gets warm @ lights without the shroud. Bill M 65 Coronet 500 'vert ---- Please address private mail -- mail of interest to only one person -- directly to that person.
