Oldsmobile 442 Restoration Guide -- 1964-onward — preview & buy

Step-by-step procedures for the 1964-onward Oldsmobile 4-4-2 / 442 restoration - the Olds Rocket V8 fitment on the GM A-body Cutlass 112-inch-wheelbase unibody in the 1964-cutlass-shell trim designation (NOT the 1971-onward 442 wedge-era track, NOT the GM B-body intermediate Centurion / Delta 88 that carries the 442 naming in different form on a different chassis); the 4-4-2 fitment (4-barrel carburetor / 4-on-the-floor transmission / dual exhaust) as a discrete hardware specification rooted in the 1964 Cutlass coupe, distinct from the 442 trim naming introduced a year later; the 442 trim naming from 1965 onward layered on top of the 4-4-2 fitment hardware where the ordered car carried both; the W-45 W-code sales-code fitment window 1968-1970 reserved for the most performance-oriented 4-4-2 / 442 fitment; the Rocket V8 family (the 400 cu in from 1965, the 455 cu in from 1968, the 350 cu in from 1968-onward on lower-trim 442) versus the Buick 400/430/455, the Pontiac 400, or the Chevrolet big-block - Olds-side castings are not interchangeable across GM marque lines; the GM A-body shared chassis with the Pontiac LeMans / Pontiac GTO / Chevrolet Chevelle / Buick Skylark on the 112-inch-wheelbase unibody, with Olds-side cowl tags and Olds-side trim tags remaining marque-specific even where the body shell is shared; the 442 grille pattern with the 442-specific rear-deck trim and the 442-specific interior decor and the 4-4-2 fitment hardware running on the Rocket V8; the 442 trim tag decode by year with format conventions changing in 1968 (when the W-45 window opens) and again in 1971 (when the 442 trim continues outside the W-45 ordering code); the W-45 sales code on the build sheet recorded alongside the trim / paint / engine codes distinct from the fender-badge-only authentication; the 1968-onward W-45-ordered 442 with the W-45 console plaque documentation in the interior; the 1968-only electro-luminescent-cluster analogue document for the Olds 442; and the Olds-side 442 parts-catalog spread versus same-year A-body (Pontiac LeMans / Pontiac GTO / Chevrolet Chevelle / Buick Skylark) - the 442 trim designation, the W-45 sales code, the Rocket V8 castings, the 442-specific grille and rear-deck trim, and the trim-tag authentication table.

Includes torque charts, fastener grades, and an A-body trim-tag authentication appendix.
