Big Block Fan Shroud replacement

The 68/69 radiators have different part numbers, but appear to be identical, hose inlet/outlet location, etc.
Compared to the 68/69 the upper hose on the 67 is roughly 1.75" to the left, other than that identical except for the overflow hose tab which is in the same location just flipped.
The 67 cars don't have a fan diameter listed, but the only fan smaller than 18" are for a small number of 6 cylinder cars.

Since the upper hose doesn't appear to interfere with the shroud, I don't see why the reproduction one would not fit a 67 radiator.

With a 22" radiator and an 18" fan I'm not sure a shroud is going to have a big impact anyway. Especially since I'm going from a flex fan to the 18" clutch fan, and the car didn't already have any overheating issues.

Along with the prospect of melting a $170 shroud to my fan/radiator, I think I'll pass for now - but I learned a few things.
