Just thought I would post up on this.....I have now had 3 different hipo fan blades, purchased from 3 different suppliers and made by 2 different manufacturers.....all three have thrown a blade at one of the "star points" that the blades are riveted to. Just sheered off. 1 the blade hit the strut support on the passenger side, went up under the battery and dented the battery tray, second time it hit the support in the center of the hood right at the crest (but didnt dent the hood on the outside), third time it hit the strut support on the other side and went out the bottom. EVERY TIME it took the fan shroud with it. I have no idea how it didnt hit the fender apron/engine bay walls, belts, hoses, BATTERY, or anything that was more important. This has been over the last 4 years.....I have never heard such a thing, but I thought I would let yall know.......I have given up on looking somewhat original and going with a flexalite 1300 fan in the near future......
