i have an 8 blade fan that my dad said he took off an oldsmobile. what oldsmobile had one? it looks to be a factory fan and looks like several other gm fans in it's design. this is the only 8 blade fan i have ever seen.

 

I agree, 7 blade is the most I've seen. Would you post a picture so we can see it?

look on the back of the mounting flange if there is a clutch attached, and post the numbers.

 

it is at my parents house. i will bring it home and get a couple pictures.

 

WOW. i sure need to learn how to count. i thought this was a 8 blade fan. i just got it from my parents house and found that it was a 7 blade. what all would have got a 7 blade fan?
