Fan Blade Identification
How can I identify or date a fan blade ? I have what I believe to be a 70 LT-1 fan blade , 5 blades 17 1/2 dia. The only marking on it is the letter " H ".

The ones I've seen have the part number stamped on the back of one of the blades. Not sure about an actual date

according to my ncrs book, cars without A/C use a 5 blade fan without a date code, a/c cars have 7 blades
