    GMC Jimmy — First generation (1983–1994)

    The first-generation compact GMC Jimmy is the S-15 Jimmy of GM's joint S-10/15 Blazer/Jimmy books (2WD S10516 and 4WD T10516 tailgate models, body E55); Wikipedia's S-10 Blazer article (the GMC Jimmy title redirects there) dates the generation 1983–1994, adds 4-door models for 1991 and says the S-15 prefix was dropped for 1992, and NICB's 1987 and 1991 VIN manuals list the S/T Chevrolet Blazers and GMC Jimmys with the utility lines. No GMC order guide or kit is in the repository for these years, so the rows come from the Chevrolet S-10 Blazer Heritage kits, judged book by book: the 1983 and 1988 books and the 1989 S/T Blazer/Jimmy data book (held twice, as the 1989 file and as the file misdated 1990, which dates no 1990 row) are joint books; the 1984–1987 books are joint except their Chevrolet-only pages (1984 pp.19–24, 1985 pp.1–6 and 27–36, 1986 pp.5 and 11–28, 1987 pp.1–20, headed S-10 Blazer with only Chevrolet names), which date no year here, while the 1987 p.41 and 1988 p.5 price pages count as joint because they print the Sierra Classic and Gypsy names; the 1991–1994 books are Chevrolet-only, so those years carry only the 4.3L V6 (LB4) as a single-source row (the 1994 book sells the enhanced 4.3L L35 only inside the R8Y enhanced powertrain package, so it has no row), and 1990 and 1993 carry no rows. On the joint pages the GMC trims are Sierra (YC1, the 1989 base trim), Sierra Classic (YC2), Gypsy (YC3) and the Timberline package (YH9, 1987–1989), and the engines are the 1.9L L4 (LR1, California, 1983–1984), the 2.0L L4 (LQ2, 1983–1984), the 2.8L V6 (LR2, 1983–1985), the fuel-injected 2.5L L4 (LN8, 1985 and 1987–1988) and 2.8L V6 (LL2, 1986–1989), and the 4.3L V6 (LB4, 1988–1989). Years that the merged S-10 Blazer doc takes from the Chevrolet-only order guides, or from price lines (With/Without), package contents, exclusion remarks or the 1987 snowplow specification sheet, are not claimed here, so many rows carry fewer years than that doc's; tire codes, seat trims, paint colors and stripe colors are not listed.
