    Chevrolet S-10 pickup — First generation (1982–1993)

    The rows come from the GM Heritage restoration kits of the S-10 pickup: the 1982 model selector and option pages, the 1983–1988 S-10/S-15 pickup option price pages, power team charts, engine, color and paint pages, the 1988 and 1989 dealer order guides, the 1989–1992 data book option charts (2WD S and 4WD T models, regular cab and extended cab) and the 1993 Light-Duty Technical Guide pages; the 1983–1990 books are joint S-10 and S-15 books, so their trim names pair Chevrolet and GMC names (Durango/High Sierra, Tahoe/Sierra Classic). Their engines are the 1.9L L4 (LR1) and 2.8L V6 (LR2) to 1985, the 2.0L L4 (LQ2) in 1983–1984, the 2.2L diesel (LQ7, with B3J) in 1984, the fuel-injected 2.5L L4 (LN8 in 1985–1990, L38 in 1991–1993), 2.8L V6 (LL2) from 1986 and 4.3L V6 (LB4) from 1988; the trims are Durango (YC1), Tahoe (YC2) and Sport (YC3, discontinued for 1989), with the EL economy model (X81) from 1986. NICB's 1987 VIN manual lists the S-series as the small conventional cab line. Tire codes, seat trim codes and exterior paint color numbers are not listed here.
