Stock clutch fan setup does not use a spacer. It should be a 5 to 7 blade fan, you can find them pretty cheap on Ebay if you don't need a dated one. The stock low horsepower fan is a 4 blade fan with the spacer I believe. Go with the clutch fan setup. It's an 18" fan but you definitely need to run the correct fan shroud to expect the setup to work properly.
