Just joined the forum after spending countless hours trying to figure this out. I am co-owner of a 77 Ford Pierce bodied fire truck. Last weekend the fan assembly disintegrated and the fan put a hole in the radiator. It was towed to a ford truck dealer and they now say we need $1000 in labor and the fan assembly is no longer made so we need a $700 electric fan kit. This seems ridiculous. I've searched high and low for a replacement part but it seems our 477 equipped truck has a whole hub/fan assembly as one rather than just a blade. Can anyone help with advice, replacement parts, and/or other solutions. We can't afford 2 grand in repairs and it seems ridiculous what should be a cheap part is requiring such an elaborate fix. I have found "fan spacers" which look like they may work but the hub pattern is impossible to find information on. In these trucks is the fan connected to the water pump directly? Thanks in advance - Contribution to the forum if anyone can assist.

Ask for Norman, he's the owner and a true antique car nut (he has an incredible car collection). If he can't help, he might know someone who can.
I recently replaced my water pump. the fan is seperate. they made several different pumps ,with different bolt patterns for the fan. I found a water pump on ebay, and had a machine shop make me an adaptor.
Yeah no parts made for these any more. Just get the radiator recored at a radiator shop and the electric fan setup I used a setup from a lincoln town car fit pretty well on the 72 with the 534 its just a water truck and never leaves the yard but never overheats with the fan.
been through that, had my fan break about 20 years ago, but at that time I was able to buy a new one and the price was 425.00, I have just taken my
engine apart to redo the exhaust valves and the fan assembly is off the water pump. I can get you the thread information and then I would recommend the Lincoln town car fan clutch. I saved the one off my sedan just in case. also check the later pumps, it seems to me that the 75-78 fans mounted on the water pump pulley.
