I was browsing through the junkyard today and found a B-series Dodge van, 3/4 ton. The van was a 98 and I was looking at the fan and it had a much better array of fins than what the Dodge truck has. Just curious if anyone had install one on there truck and hows it working?

Note: the one I found was metal, not plastic but looks identical
