fan blade

[bradwallace]

I just tryed to install a new fan shroud on a 66 C10 v8, the shroud hole is 19" and the fan is also 19", can i find a stock fan smaller, or do i need to look after market?

Chevy made various sizes of fans.They made a five blade for the Chevelles that was 18".If you can find one they were the best for cooling.
