The 1963 service manual does NOT refer to a Y body Imperial, but to a Y MODEL Imperial. The letters used in Chrysler's model numbers and serial numbers do not refer to bodies in any way, shape or form They do, however, refer to a the car model or line. And there was a "Y" body Imperial - two in fact. The 1981 Service Manual lists the car bodies with the car lines beside it. It shows "J" body with Cordova (S) and Mirada (X), "M" body with Caravelle (B), Diplomat (G) and LeBaron (F), "R" body with Gran Fury (J), St.Regis (E) and Newport / New Yorker (T), and, yes, "Y" body with Imperial (Y). And if you check the 1990 to 1993 books, you will see the "Y" body as being used on 1990-1993 Chrysler Fifth Avenues and Imperials. The pre-1967 Imperial is referred to as the "D" body, while the 1967-75 Imperial used the "C" body, shared with Plymouth Fury, Dodge Polara/Monaco and Chrysler Newport/300/New Yorker. It seems to upset many that the Imperial shared its body with the lowly Plymouth Fury, but it did. Just as the Cadillac DeVille body was based on the lowly Chevrolet from 1959. The Imperial car LINE was "Y" in all years from 1958 to 1975, but the bodies were not. The letter "Y" was used for all Imperial model numbers from 1958 to 1975 and in the serial number in 1958 and again from 1965 to 1975. The 1959 Imperial used "6" in the serial number while the 1960-64 Imperial used "9".
