65Val, mean when you said the 68-69 shroud fit your ‘67 radiator perfectly? Thanks for that info. I know it fits the ‘67 radiator, but with what engine/fan? I have heard it’s the hole (that the fan fits into) that is different. Not how it attaches to the radiator. Which might be why the OP is having an issue with the 340 fan fitting in too tightly. For example, my 318 with the ‘67 radiator might need the 68-69 shroud and not the 67 one. At least that’s what I’ve been told.
