My 78 has the VIN in the door frame.
If memory seves me right, some where in the 78'ish year they came out with a Bonanza was a package that they offered for a couple of years.
Bonanza special promotional grouping of options. It was offered during the 1976, 1977, 1978, 1979, and 1980 model years, and was typically offered during the final months of those model runs. There were several packages (typically designated "A", "B", "C", etc., and respectively carrying increasing levels of included equipment) offered on a variety of truck models. Equivalent packages were offered for GMC vehicles under the "Royal Sierra" designation.With the exception of the 1980 model year, the packages for the pickups were based upon the Scottsdale trim package, and with the exception of carpeting and nameplates and discounted option prices, resembled other similarly optioned non-Bonanza Scottsdales offered during those years.The specific packages for 1979 Chevy Big 10 pickups were as follows...Package A (code YG6) included Scottsdale trim, Bonanza nameplates, color keyed carpets, striped vinyl bench seat, deluxe wheel covers, chrome grille, upper and lower bodyside moldings, clock and gauges, AM radio, inside hood release, automatic transmission, comfortilt steering wheel, intermittent windshield wipers. The total savings for package A was $200.Package B (code YG7) included all items for package A plus tinted glass, air conditioning, cargo lamp; package savings was $300.Package C (code YG8) included all items in packages A and B plus operating convenience group (power windows and door locks), speed and cruise control; package savings was $400.Interestingly, the Scottsdale offered three different upholstery choices. They were Custom Cloth, Custom Vinyl, and Striped Vinyl. The Custom Cloth and Custom Vinyl options for non-Bonanza Scottsdales included a color-keyed rubber floor mat while the extra cost Striped Vinyl selection replaced the mat with carpeting. The Bonanza default upholstery was the striped vinyl, but I believe the Custom Cloth and Custom Vinyl could also be specified for the Bonanza without forteiting the carpet.
