fan shroud part numbers 340 ??? have a fit issue

numbers i have are 2785 312
95511


bought from another member with rad said it was 69 340
well my rad is a 68 looks the same as the one i got from him.
my issue is i got a new viscous clutch fan witch measures the same as stock fan i took off well i think its the stock one 6 blade never tryed it with the shroud so i dont know if it does the same

the fan is grazing the lower part of the shroud and i would hate to cut up a nice shroud just checking if these numbers are correct for what i was told

thanks

Is that a big block shroud? The small block shroud is available aftermarket and should work as long as the water pump entrance is on the factory side. I've seen people have trouble trying to install a 67-69 shroud on a car where the waterpump has been reversed. What do you have exactly?
