A friend in Wash state is doing a resto on a 55 Crown Victoria. The car is dismantled. He asked if I knew what the correct casting #s were for the exhaust manifolds. The car is a "U" code, but I don't have a reference for that. (?)  I have the exhaust manifold part numbers  from Eickman's book, for Fairlane series & Station Wagons, L H - B6A 9431-A & B7A 9431-A for Std & O.D. trans.  R H - C2AZ 9430-A, but they aren't much use at this point in time. Anybody have a reference for casting numbers? thanks..
