Sometimes Older is Better

Back in the mid 70s I ran one of those fiberglass fans on my Roadrunner and had good luck with it. Ever since I heard about the potential risk of them coming apart I didn't consider using one again. - And I haven't seen one being used in the past 30 years. I wouldn't mind having one if I was building a 70s tribute hotrod.
I never heard of these particular ones coming apart.... the stainless bladed ones are what I fear. I had 2 of those bakc in the 70's before putting this fiberglass one on the old Ranchero, and both SS bladed fans developed cracks near the roots of the blades; I luckily caught them in time. But your point is well made: we'll inspect this regularly.
