Review on Upgraded Gray/Black Dual Radiator Fan by Derale Performance for Enhanced Output - Model 16831 by Steven Notsinneh

Perfect fit for my 65 K10 Chevy. The only downside was the mount, although it's universal I don't think it's that versatile. Luckily my radiator had mounting tabs that I riveted the block to. They fit more than perfectly, draw a lot of air and seem to do what they're supposed to. The only issue I had was changing the wire colors on a fan so it worked in reverse. So I just swapped the cables.
