7 Blade Fan with Clutch Slant 6

Ok, I found a NOS fan for the slant 6 with air. It is a special fan that has a small pitch to the blades (1/2 pitch) with 7 blades. It does not mount with a clutch, it bolts to the water pump pully just like the 4 blade fan I have now. Thanks for all the help everyone who contacted me.
