1978-2023 “letter platforms” for classic rear wheel drive Chrysler, Dodge, and Plymouth cars

based on oh2o’s 2006 list at allpar
Updated August 3, 2023

Chrysler adopted single-letter codes (A, B, C, and D) to lump cars together by platform with the 1964 model year; some of the codes were applied retroactively to earlier cars. When Chrysler bought AMC, which had two-letter codes, they added an “A” before the single-digit codes—e.g. the P body (Sundance) became the AP.

Single-letter codes for rear wheel drive cars (A, B, C, D, E, F, J, M, and R) are listed in our RWD codes page. Past and present truck body codes are in a separate page. All years below are model years. There are likely to be minor errors; please let us know, if so!
