    Chevrolet S-10 Blazer — First generation (1983–1994)

    The rows come from the GM Heritage restoration kits of the S-10 Blazer, whose 1983–1988 order guides and data books are joint S-10 Blazer and S-15 Jimmy books (2WD S10516 and 4WD T10516 tailgate models, body E55), with the 4-door S10506 and T10506 models added in the 1991–1994 pages. Their engines are the 1.9L (LR1, California) and 2.0L (LQ2) L4 and 2.8L V6 (LR2) to 1985, the fuel-injected 2.5L L4 (LN8, from 1985) and 2.8L V6 (LL2, from 1986), the 4.3L V6 (LB4) from 1988 and the enhanced 4.3L CPI V6 (L35, ordered as R8Y) in 1994; the trims are Tahoe (YC2) and Sport (YC3), the High Country package (YH9) in 1987–1989 and Tahoe LT (YC9) in 1992 and 1994. The kit filed as 1990 is the 1989 data book (its pages are dated August 1988 and revised January 1989, and it still lists the 2.8L V6), so no year is claimed for 1990; the correctly labelled 1989 S/T kit (chevrolet/1989-Chevrolet-Blazer.txt) holds the same book, so 1989 is cited to its pages (pp.16-20 match the 1990 file's pp.14-18) and the 1990 file is cited only for GT4, G80 and D96, whose 1989-labelled pages print the code in a form the checks reject; the 1993 kit's only listed page is a specification sheet with no RPO codes, so 1993 is not claimed. NICB's 1987 VIN manual lists the S/T Chevrolet Blazers with the utility series; tire codes, seat trims, paint colors and stripe colors are not listed here.
