aiight...i'm still waiting for my parts but i was looking at the chiltons manual and they said that if i'm going to update the radiator fan to a flex fan...then i'm going to need a "spacer" between the clutch and the water pump hub. Do i really need this piece in order to use the flex fan? and if so how much will it cost and where can i get one...hopefully somewhere in my hometown

thanks for replies
Allan
