Documented applications

Century — A-body (1982–1996)

1985–1988 Single-source

Shared A-body code, cited from the Chevrolet Celebrity kits; no Century source names it, so the row rests on the kit pages alone; 1984 is left out because the page prints the code as UAT and 1989 because its only weight page prints a model year of 1988; the 1987 page is cited although it prints UAl (lower-case L, read as UA1, rule 9(d)); the 1988 page prints UAI, read as UA1
