A deserved bump so we can get some more info added.

[classicchev]

Where are the RPO codes for the 67 72"s

[americanmusc1e]

believe it or not but the aluminum part of the 69 and 70 grilles are different, look at the space between the parklights and the headlight buckets, if needed I can post pictures

LMC only sells 69 grilles

[gcburdic]

yep american muscle....please post pics of the difference please....Thanks!!!

[americanmusc1e]

a '69 grille(this one is from LMC, i am too lazy to go outside and take pictures)


a '70 grille

a small difference but still a difference

[chevy29267truck]

nice but if GM played there cards right the 67 would have been its only year it has the small back window no lights on the front fenders or the side of the bed the one year arm rest same thing for the vent windows seat belts too and was the last year for the 283 chevy engine

[sweetnlow67]

what are the differences in the doors from a 67-72???

[kingsolver72]

72 has a retaining screw for the wing/vent window..I believe the 72 window crank/regulator is longer.

I've always wonderd if the "All Chrome Grill" on a 71 GMC, was interchangable with the "Black Painted Center Grill" on a 72.

I'd love to put the all chrome Grill on my 72!

Chevrolet C-10 stepside
GMC C/K
Chevrolet C-10 CheyenneA 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. The majority of 10 and 20 series Chevrolet trucks from 1967 to 1972 were built with a coil spring trailing arm rear suspension, which greatly improved the ride over traditional leaf springs. However, leaf spring rear suspension was still available on those 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 cu in (4.6 L) V8. The optional transmissions were the 4 speed manual, the Powerglide and the Turbo-Hydramatic. 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, the 3/4 and 1 ton trucks came with an 8 x 6" bolt pattern.

In 1968, the 283 cu in (4.6 L) V8 was replaced with a 307 cu in (5 L) and a 310 hp (231 kW), 396 cu in (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 front of the 1967-68 hood was slightly less (approx. 65 degree angle)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 saw a new V8 engine: a 255 hp (190 kW), 350 cu in (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, and a more modern looking 2-spoke steering wheel with plastic horn button replaced the previous year's 3-spoke wheel with chrome horn button. Also new this year was upper and lower side moldings, which added another two-tone paint option. These were standard on CST trucks, and optional in any other trim level.

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 highlights that break the appearance into 6 separate sections.

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, carpet, chrome trim, and upper and lower side molding and tailgate trim. 1971 was the first year for AM/FM radios factory installed. 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 many 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, although the 396 was now known as the 402 V8.

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 vinyl-covered flat door panels were no longer available; all trim level door panels were molded plastic with integral armrests and wood grain inserts on Cheyenne and Sierra trim levels. For restoration, it should also be noted that the door and window cranks were slightly longer due to the molded plastic door panels, and the vent windows were now secured with a single screw on the inside of the door, thus differentiating it from the 1971 model year.

Do you know which manual 3spds had OD? I'd never knew any of these trucks had OD.

67'-70' bumpers were the same on front71'-72' have turn signals in them. i'm trying to id a 67-70 C 20 chassis and is their a way to tell without the body what hand brake system it used as that would narrow down my search. the frame has ps. and is dimpled for it. with the info so far i'm thinking 69'-70' chassis. the brakes are drum. it's under a 59' apache right now with factory style flatbed (the kind with metal band wrapped around the perimeter) soon to be replaced with apache shortbox. thanks

[leh72super1500]

I believe the below eyeline mirrors (not the camper mirrors) changed in 72 from long support arms to a short arms. Also the smaller standard mirrors changed in 71 to the chrome sport mirrors.

[TBONE1964]

Wow, I read though every single post hoping to find someone that would mention that a 67 only came from the factory with a drivers side sun visor. My 64 is the same and I believe that changed in 68. Look at some 67 cabs and I would bet there are no holes on the right side for a sun visor. As always, please correct me if I am wrong. Although the body style is completely different, you will find a few carry over things from 66 to 67.

[rico7769]

my 67 gmc has holes in both sides for the visors.
Also 67 grill was the only one that the letters "GMC" were inset into and following years they moved to the hood mounted lettering

a '70 grille

a small difference but still a difference

I do not believe the GM is going to retool that minor of a change on the grill surround between 69 and 70. I just looked though a lot of photos doing a google search and I dont see any difference other than 69's did not have that thin black strip on the outside of the parking light lens. Because repop parts cannot duplicate the original exactly, the repop companies have to make minor changes in there tooling.

I am glad you mentioned it, now I know an original from a repop and I am sure some show judges do too.

I had a friend in high school that had a 67 GMC 3/4 ton 2 wheel drive ( as base model as you could get). His truck only had holes on the drivers side. I thought that was odd. I wonder if it is a production date change.

Anyone else have input. Now I am curious.

[budman k20]

In case it has not been already mentioned the 67's had bullseye backup light lens. The rear view mirror arm is also different than latter years. The seat could fold forward.

Some base model 67s came with driver visor only. The rear wheel opening is also the same as short beds on 67 longbeds. The front bottom of the opening comes to more of a point. Heater control is different on 67s also. 67 cst had one year only steering wheel cap. All interior knobs were also different on 67s.

Yes, as stated the two pictures show the difference between a repop grill, and an original 69-70. The only difference with the 69-70 grills that is confirmed is the inner plastic portion. I have seen both 69 and 70 outter grill surrounds that were claimed original, that have certain portions not painted black. That could be due to different manufacturing plants. Also, the headlight bezels are steel, and painted black on the 69-70 models.
