1983–1984 Factory-verified

1984: California only, sedans (power-teams page 5), and listed for the sedan (1BL69) on the weight sheet (p.38); the 1983 page 16 prints LDS; the 1985 weight sheet (p.40) and air-conditioning remarks (p.39) still list it for the sedan (1BL69), but the 1985 power-teams page (p.7) and engine and transmission page (p.18) print only the 4.3L V6, LG4 and LF9, so 1985 is left out (not disputed: those pages also omit the police LM1, so the omission is not conclusive)
