Purchased a shop manual for all model 1969 Cadillacs off of ebay. It arrived today. What a god send. This thing has everything about the 472 you want to know and since my hearse is a 69 I'm in heaven. New 4 row radiator with new flex fan and fan clutch assembly with new water pump and thermostat and all new belts going in tomorrow. She should be running cool now. This summer thinking about adding AC this shop manual will sure come in handy and with the upgrades to the cooling system I should be good to go. Thanks to all who have helped.
