Could anyone please help me out? What fan do I have to use - will say what diameter and how many blades - for my 68 400cci (YS coded) without AC? The car has a correct 4bbl quadrajet and power steering (if this should be of concern) and I´m using the correct GM fan shroud (and a non-stock but exact fitting RodneyRed radiator). Driving a car without AC I already was told NOT to use a fan clutch.

Concerning the fan shroud I think it should be a 19" fan, correct? So I only have to know how many blades... And where to get it...

YearOne and ClassicIndustries are selling 6-blade Flex-a-lite OEM fans, both times showing the same picture. But Year One (# FA24) is telling they are an upgrade for direct-drive 4-blade fans, Classic Industries (#FL5719) is talking about using them together with a fan clutch... And Ames (# FP191HA) is showing exactly the same pic, too, labeling it for use w/o clutch but is selling it twice as expensive as the other two suppliers (USD 69.00 vs. 34.95)...

Any input would be appreciated!

Thanks and best regards

Thomas

PS: Will I need a fan spacer, too? And if so what length should it show (GM offered 1 1/2", 1 15/16" and 2 9/32", only the first is available at Ames)?
