With Chrysler, the original A body was the 1960 Plymouth-Dodge-DeSoto-Chrysler body. The B body first appeared for 1962 (Plymouth and Dodge) and for 1963 the new Valiant and Dart was called the A body. The former A body officially became the C body with the 1965 models and the body-and-frame Imperials became the D body. Chrysler used the first letter of the car line name for the model number and VIN letter, usually. Plymouth, Dodge and Chrysler were simple,.as were the Valiant (except 1960 which was X) and Barracuda. The Dart's L actually stood for Lancer (although the 1961 Lancer was W). The Belvedere (R), Coronet (W), Charger (X), Challenger (J) and Cordoba (S) all used different letters as the Barracuda and Chrysler had already taken the B and C. Other exceptions were DeSoto, which used S for its model numbers, the export DeSoto Diplomat which used "F" in 1958 and 1959 and the Plymouth-sized Dodge which used "E" in 1958 and 1959. By the way, the car line letters were used in the 1958 serial numbers (second digit - C,D,E,P,S,Y). The Canadian Plymouth-sized Dodge used "E". Letters reappeared in 1964 for the Dart V8 (L) and U.S-built Valiant V8 (V). In 1965 letters were used in U.S. Mopar serial numbers for all cars with V8 engines. The Canadian-built 1964 Valiant V8 serial number started with "7" and all Canadian-built Chryco cars had a letter as the first digit in the serial number for 1965. >From 1959 to 1964/5, instead of letters, Chrysler used numbers for the car lines, with the numbers changing in 1960 and again in 1961 and 1962. 1960 saw the addition of the Valiant, 1961 the Dodge Lancer and 1962 the disappearance of the DeSoto. The use of letters was needed as the introduction of the Valiant and Dart V8 models meant Chrysler ran out of numbers. With the 17-digit serial numbers, Chrysler adopted a letter for the make (2nd digit : A -Imperial, B - Dodge, C- Chrysler, E - Fargo, P - Plymouth. In 1988 E became Eagle and J for Jeep was added) and a letter for the car bo dy (5th digit) in 1981. In 1982 the 5th digit again reverted to the car line but in 1989 went back to the car body. By the way, all General Motors cars used the letter "G" as the second digit. The 3rd digit, by the way, is for vehicle type (car, truck, MPV, etc.) General Motors body designations were not in reverse. The "A" body first appeared in 1937 and was used by Chevrolet. GM of Canada added an "A" body Pontiac Special Six for 1938, followed by the U.S. Pontiac Qualtiy Six and Oldsmobile series 60 in 1939. Buick used the A body for the 1941 and 1942 Special series 40-A. The larger B body appeared in 1937 as well and was used by Pontiac, Oldsmobile, Buick and LaSalle. By 1940 it was used on the Pontiac DeLuxe, Oldsmobile series 70, Buick Special series 40, Buick Century series 60, and LaSalle series 50. Cadillac started using the B body in 1941 when the LaSalle series 50 became the Cadillac series 61. 1940 was the year GM came out with the C body, and was used on the Pontiac Torpedo, Oldsmobile series 90, Buick Super series 50, Buick Roadmaster series 70, LaSalle series 52 and Cadillac series 62. In 1942 the Cadillac Sixty-Special began using the C body. That was also the last year for the unique bodies used on the Buick Limited series 90, Cadillac series 67 and the Cadillac series 63. When GM designed the B body for 1950, the C body was basically an extended B body. By taking the B body, extending the chassis frame, using the series 62 rear fenders and trunk area, GM created the Cadillac series 75 sedans and limousines. In 1959 the A body disappeared as the Chevrolet, Pontiac, Oldsmobile, and Buick (except the Electra 225) all used the B body, GM lengthed the wheelbase 4" (all in the rear), gave it unique rooflines and created the C body which was used by the Buick Electra 225 and all Cadillacs except the 75. The Cadillac 75 was again an extended B/C body. The Oldsmobile 98 started using the C body again in 1961. It had been using an extended-trunk version of the B since 1952. General Motors re-introduced the A body with the intermediate Chevelle, Beaumont, Tempest, F-85 and Special in 1964. When GM downsized in the 1970's, the Malibu, LeMans, Cutlass, and Skylark body was still the A body. It shared nothing with the B body which was used by the Chevrolet (Impala, etc), Pontiac (Catalina, Parisienne, etc.), Oldsmobile Delta, and Buick LeSabre. The C body was still an extended B body and was used by the Oldsmobile 98, Buick Electra, Cadillac deVille and Fleetwood Brougham. The Cadillac 75 was again an extended B/C body. The square roofline of the A body Bonneville/Grand LeMans shares only the design theme of the square roofline of the B body Bonneville. The A body was narrower and shorter than the B body.
