Unfortunately I have no books to check the vet part number for the fan may be someone else can assist there. I do know the vet used the same DG water pump pulley as the 67/68 Z 3770245 since I just sold a NOS one to a vet guy for his small block and he was real interested for me to search through my fans.
Also I think we had a 68 l-72 and a regular 68 396 350 hp with this fan (3871276). I remember looking for a replacement clutch unit for the 396 and the replacement ones would not fit the fan blade but the one off the 68 l-72 worked.
We don't need 3000 dollar fans currently running on or put away for old 68 BB , if that is possible.
