1977 Oldsmobile Notes

Downsized B/C-body Delta 88 / Ninety-Eight / Custom Cruiser (coupe 37, sedan 69, wagon 35); Cutlass keeps the Colonnade A-body one more year.
The 455 V8 was dropped after 1976 and replaced by the 403 V8; the Oldsmobile 350 Diesel began in 1978, so there is no 1977 diesel VIN code.
Same 13-character alphanumeric VIN format as 1972-1975; year code '7' at position 5 with a LETTER series at position 1 (1967 uses digits).
COVERAGE: completed from the GM 1977 Passenger VIN System card -- every 1977 Oldsmobile series letter (Omega/F-85/Brougham, Starfire/SX, Cutlass S/Supreme/Salon/Supreme Brougham, Vista Cruiser, Delta 88/Royale, Custom Cruiser, Ninety-Eight Luxury/Regency, Toronado XSR/Brougham); the earlier pilot tabled only seven observed keys
Toronado XSR (series W) is the wraparound-rear-window variant; Starfire SX (D) is the up-trim Starfire.
