Lol its more of a slight knick than a ding, nothing some fine sandpaper wont take care of.
One thing i noticed is how much lighter the 5 blade is compared to the 6, i wanna say the 6 blade weighs twice as much, that alone should help prolong water pump bearing life. Now just time to order the clutch......... and water pump........and thermostat lol
Edit: i just looked, i actually had a 7 blade fixed fan, # 46237
No wonder why the 5 is lighter lol
