S5 fan blade on S4?
 

Not sure if this has been covered before. Will a S5 fan blade work on a S4 with no problems? I know it will bolt directly to the S4 fan clutch, but will it have any clearance issues with the stock fan shroud or any other issues at all? This is going on my '87 T2. Thanks.

I f I remember right the only major difference is the number of blades. Like 6 to 8. Or something close to that. But measure the diameter of both and if they are the same then you should have no problem.
