Fan blade on Dart broke today

Boy I have a flex fan on mine now and I bought a 7 blade fan and thermo clutch, and now I am worried this might happen to me, did you have a shroud on?? and how many blades was it and did you have a thermo clutch or was it direct drive??

Direct drive 7 blade flex fan with shroud. Missed the radiator and shroud and was laying on top of the power steering pump. I wanted to reuse this fan on the new motor because it kept the temp at or below 200 all summer long. It worked well.
