Do You Know Your Chevy???

[70cst]

I found this while surfing this morning. I thought this was interesting reading... How accurate is the info...you tell me

The C/K is the name for Chevrolet's full-size pickup truck line from 1960 until 1998 and GMC's full-size pickup truck line from 1960-1988. The first Chevrolet pickup truck appeared in 1924, though in-house designs did not appear until 1930. "C" trucks had two-wheel drive while "K" models had four-wheel drive. The C/K light-duty pickup truck was replaced with the GMC Sierra in 1988 and the Chevrolet Silverado in 1999; the Chevrolet Silverado HD and GMC Sierra HD heavy-duty pickup trucks followed in 2001.

1967 A new, more modern look came in 1967. It was with this revision of the C/K truck that General Motors began to market trucks as general transportation rather than as work vehicles and nothing else. One 1968 magazine ad ran with the line "A Chevy pickup is built to be womanhandled." This was evident throughout its construction; the majority of 10 and 20 series Chevrolet trucks from 1967 to 1972 were shipped with a coil spring trailing arm rear suspension, which greatly improved the ride over traditional leaf springs. However, leaf spring rear suspension was available on all trucks, and standard on 30 series trucks. GMC models came standard with leaf springs with coils springs optional; all four-wheel drive models (Chevrolet & GMC) had leaf springs on both axles. The standard drivetrain came with a 3 speed manual transmission and one of two engines; the 250 in³ straight-6 or the 283 in³(4.6 L) V8. The optional transmissions were the 4 speed manual, the Powerglide and the Turbo-Hydromatic. The 292 in³ straight-6 and the 327 in³ V8 were the optional engines. The 1/2 ton trucks came with a (6 x 5.5") bolt pattern. However the 3/4 and 1 ton trucks came with (8 x 6.5") bolt pattern. 1968 In 1968, the 283 in³ (4.6 L) V8 was replaced with a 307 in³ (5.0 L) and a 310 hp (231 kW) 396 in³ (6.5 L) V8 was offered for the first time. The most visible change in differentiating a 1968 from a 1967 was the addition of side-marker reflectors on all fenders. Also, the small rear window cab was no longer available. The GMC grille was revised, with the letters "GMC" no longer embossed in the horizontal crossbar. Another note for restoration is that the 1967-68 hood was more sloped and without 67-68 fenders, the hood will not fit 1969-1972 models. Another addition was the Custom Comfort and Convenience interior package that fell between the Standard cab and CST cab options. 1968 was also the year that Chevrolet celebrated 50 years of truck manufacturing. Also in 1968 the 3/4 ton Longhorn model was added to the lineup. The Longhorns were designed with a strong 8 1/2 foot box that could hold a big slide-in truck camper. 1969 1969 saw a new V8 engine: a 255 hp (190 kW) 350 in³ (5.7 L). Along with the new engines came a new grille design for Chevrolet trucks and a more upright hood for both Chevrolet and GMC trucks. A utility variant known as the K5 Blazer was also introduced with a shorter wheelbase of 104 inches (2,642 mm). The GMC version, known as the Jimmy, was introduced the same year. Some internal cab changes were also made, most notably the switch from a hand-operated parking brake to a foot pedal. 1970 The only noticeable change for 1970 was a minor update to the Chevrolet grille. At first glance, the 1969 and 1970 grille appear identical. However, 1970's plastic inserts actually have highlites that break the appearance into 6 separate sections. 1971 Several changes occurred in 1971. First came another new grille design (the "egg crate") for Chevrolet trucks and black paint over portions of the GMC grille. Second, an additional trim package was introduced: the Cheyenne. On GMC models, this was referred to as the Sierra. These packages consisted mostly of comfort features — nicer interiors, more padding and insulation, AM/FM radios, and two-tone paint with side molding options. Finally, the front brakes on all light-duty trucks were switched from drum brakes to disc brakes, resulting in much less brake fade under heavy use. While all prior C/K half-ton trucks had used a six-lug bolt pattern (6 x 5.5") for the wheels, two-wheel-drive models switched to a five-lug pattern (5 x 5" bolt circle) common to Buick, Oldsmobile, Pontiac, and Cadillac passenger cars. The 1/2 ton 4 x 4 retained the 6 lug bolt pattern. This bolt pattern would remain the standard through the end of the C/K series (along with the Chevrolet/GMC vans). Also, Chevrolet changed the 396 V8 emblem designation to 400 V8. The change was only cosmetic. 1972 1972 models were virtually identical to 1971 models with the only change being that the rear view mirror was glued to the windshield instead of being bolted to top of the cab, and metal or plastic flat door panels were no longer available; all trim levels had a more sculpted molded plastic door panel with integral armrests and wood grain inserts on Cheyenne and Sierra trim levels.

Trim Levels
C/10 - Base Model
Custom/10 - 'Mid Level'
CST/10 - 'Top of the Line' (CST=Custom Sport Truck)
1971:

Custom/10 - Base Model
CST/10 - 'Mid Level'
Cheyenne/10 - 'Top of the line'
Late 1971, 1972:

CST/10 - Base Model
Cheyenne/10 - 'Mid Level'
Cheyenne Super - 'Top of the Line'
Cheyenne Highlander - Special 'Above top of line' package
A 10, 20, or 30 on the emblem indicates 1/2, 3/4, or 1 ton trucks.

GMC models form 1967 to 1970 used the same trim levels as the Chevrolets, except that the GMC trim levels were 1500, Custom 1500, and Super Custom 1500. Starting in 1971 this changed to:

Custom 1500 - Base
Super Custom 1500 - Mid
Sierra 1500 - Top
And for late '71 and 1972:

Super Custom 1500 - Base
Sierra 1500 - Mid
Sierra Grande 1500 - Top
Sierra Highlander 1500 - Special extra top package.
On the GMC trucks 1500, 2500, and 3500 designations were used to indicate 1/2, 3/4, and 1 ton trucks.

In both series, the 'Highlander package' included special color-coordinated houndstooth cloth inserts and additional trim colors and insulation.
