The fan doesn't fit. Blades are damn sharp though. I got it, measured clearance from the threaded nub that holds the stock fan on to the rad and it looked to be 4 1/4 inch, taurus fan from what I could get for a measurement seemed a hair smaller so I thought I was good. Cut up the taurus fan, get it all mounted, goto put it in doesn't fit. Bring it back, readjust, put it in, doesn't fit. The threaded nub keeps getting in the way from feeding the shroud all the way in. I throw everything in the truck, goto the shop at work. Goto grind the damn nub off but it looks like the plate that holds the pully on there is threaded onto a shaft that comes outta the water pump, so can't grind it down or the water pump won't work. So I try to compress the fan blades tighter onto the motor so I can take a little off the shaft that holds the blades on, it's like 1/16 of an inch I need here. Well the (enter much explicit language at high volume) fan blade assembly broke off. $70 fan is now junk. Woooo friggin hooooo. The motor just just slightly too large to fit, unless a water pump without that nub can be bought and put in.
