What is the correct fan to radiator clearance?
Spacer depths for non-clutch fans depended on blade width.
Should be room for a correct thermal drive clutch that is the same dimensions as a the factory unit.
Problems come when using the water pumps with the longer snout. But even then with the correct radiator there is room. With a later square top radiator, what I did was resolder the side mounts so the top tank was as far forward as possible. That gave enough room for the MP clutch and 5 blade fan. What your doing is better. Practically the same as factory. (And since then I've changed to a correct type radiator with 70 bottom tank).
