[Big hammer]

Not all of the original fans are made the same! Ford must of known of the cracking problem and in late 31 changed they way they manufactured them. Remember in the late 70's ford's fan blades breaking off and going thru hoods, I had a Mercury and it was missing a blade, no holes anywhere! I asked for a replacement and they didn't have one and not covered under recall, 6 weeks later I installed the new one, then about a year later ford reimburse me for the fan, but not my time.
