The Diffference between the 67-72 Chevy Trucks

I posted this for any and all to add to it what ever the changes were that are not mentioned below between the years from 67-72 .

The purpose is so any or all can copy and paste these differences and keep them for their own personal records.. I have read up on these 67-72 trucks from many writings and every once in awhile you people will write something new that is not in any one writing about these trucks,, this is what I would like to have ,,all right here to read...

I would appreciate any responces from you for my records so when I leave this world I can leave my Children the very best records from this FORUM that man can find.. Maybe some of you would like them also .. thx Larry

------------------------------------------------------------------------

With the introduction of the 1973 model year, we realized that 1972 was the end of an era for all American cars and trucks. The series of Chevy trucks that was produced from 1967 to 1972 was popular for many reasons.
These were real trucks. They didn't pretend to be big cars. (That came later.)

For those of you who are learning about these trucks, it's fairly easy to tell what year they are. The six years of production, from 1967 to 1972, are divided up into three groups of two years. We have the '67-'68 trucks, the '69-'70s and the '71-72s.

1967 and 1968 trucks shared the all-new body introduced in 1967. When I first saw a '67 I decided right then I'd have one someday. The only real difference between the two is that the '68s had the federally-mandated side marker lights that are found on all American cars and trucks from that year on. The 1967 Chevy trucks had some of the nicest styling we'll ever see on a truck. The early '67 pickups came with a small back window that was only available that year in this series of trucks.

1969 and 1970 Chevy trucks differ mainly in having new front end sheet metal. Gone is the sloping hood that was unique to the '67 and '68 trucks, replaced with a version that has a more upright leading edge. The '69 and '70 models are easy to find, and since they lack some of the features introduced in 1971 they are less expensive to buy than the '71 and '72 trucks.

The hood and front fenders interchange between 1969 through 1972 trucks, with the only difference being the mounting holes for the bowtie emblem on the '69 and '70 hoods, which was moved to the inner grille on the '71 and '72 models. Many of the other parts also interchange, except for the wheels on half-tons, and the front brakes.

1971 saw the introduction of front disc brakes on all Chevy light trucks. That year, all half-ton pickups and Suburbans were built with five-lug wheels in a five-inch, "five-on-five" bolt pattern. (This bolt pattern is shared with some GM full-sized cars.) The 1971 and 1972 trucks were given new inner and outer grilles that lacked the center bar used on the '69 and '70 models.

1972 was "the last of the all-steel trucks", since interiors were almost completely covered with plastic starting with the '73 trucks. The trend was for the industry to produce trucks that provided the comfort and luxury found in full-size cars, with power windows being offered for the first time in Chevrolet trucks.

There's no doubt that the trucks that Chevy produced between 1967 and 1972 are classics. Their simplicity, a good supply of original replacement parts and the wealth of reproduction and aftermarket parts for them combine to ensure they will be popular for a long time.

Re: The Diffference between the 67-72 Chevy Trucks

71 also had a raised pad where the rearview mirror mounted on the roof. 72 had the plastic door panels and rearview mounted to the windshield.
67 could be had with the "panoramic" rear window option. Big glass.
No power windows that i have ever seen factory.
There are other little things but you basically have it covered.

Re: The Diffference between the 67-72 Chevy Trucks

What year was the 402 an option? How about when Cheyennes debuted, when Customs ended? What about the year C5s came into being (or ceased)?

Good write up, GOPAPA.

396 was available in 68 and 69. In 70 it was badged as a 400. Available thru 72.
Cheyennes came out in 71.
69 was the first blazer, and 70 the first jimmy. I think 2wd was in 70.
I "think" the customs were available in all the years.
I am sure i will be corrected if incorrect.

Re: The Diffference between the 67-72 Chevy Trucks

67-68 had a hand operated parking brake. 69-72 had a foot operated parking brake. A couple of minor changes were required in the cab.

The parking brake cable exits the cab in a different spot than on the 67-68, and the fuse block sits horizontal on the 69-72 instead of veritical like on the 67-68 to clear the parking brake foot pedal.

The 67's had different vent wing knobs, and the dash and maybe window crank knobs were different also, maybe they were carried over from the 1966 model year.

Also the outside door handles are unique to the 67 model year. Although the outside looks exactly the same, the mounting screw angle is different on the inside of the door. Outside door handles from a 67 will not fit the 68 and up doors, and vice-versa.

Re: The Diffference between the 67-72 Chevy Trucks

I work with a guy who is the original owner of a '67 LWB Chevy. It has a 283, stick and very little else. Small caps on the wheels. Paint is silver with a white top. The interior is red. When you open the doors, the inside of the doors and the jambs are red, too. It was like that when he bought it, so it has to be factory. I never noticed on any others whether or not that was the case with them. The '68's had just come out when he bought his for $1750 (new). He wonders if the door paint is an early '68 trim thing or if it is truly a '67 feature.


Anyone else?

Re: The Diffference between the 67-72 Chevy Trucks

68 & 69 had federally mandated "side markers" that were reflectors.Some `69s had lights.Someone correct me,they were either an option or late year change.

Re: The Diffference between the 67-72 Chevy Trucks

Power steering in 1967 was a ram-style system.
The design of the ignition switch bezel was unique to 1967.
At least through 1968, throttle was controlled through mechanical linkage rather than a cable.
Small journal 327 offered in 1967.
Large journal 327 offered in 1968-69 only
and were all 2 bolt main blocks.
SBC 350's replaced the 327 in 1970.
1967-68 bench seats offered full-depth foam and a tip-forward design
and the 1968 Custom package could include a cloth interior
and padded door panels.
Armrests changed to full depth style in 1968.

I think 1968 was the first offering of two speed wipers standard(?)

Re: The Diffference between the 67-72 Chevy Trucks

Alright first post here.

I'm getting back into the c10's and am looking at a 69 gmc stepper. Are there any major reasons that I can't switch to a 67-68 front end?

Thanks,
Mike

PS Been browsing a lot lately and I must say you guys a have a great community going here.

You need the grille, hood, fenders, and I believe the core support for the 67-68 nose.

Great description!

Why does LMC list them as interchangable 67-72?

I think some 1968,s were the same as the 67,s My 68 has this door handel and I had to rebuil them cause nothing in my parts collection would work. My truck was built in Canada so this may be why I don't know but the doors are original to the truck.

Re: The Diffference between the 67-72 Chevy Trucks

my Father was a salesman for a Chevy dealer in the early 70's. And one thing the realy used as a saling point on the 67-72 1/2 ton with coil springs was the ride. The ride of the coil springs was so much better then that of a Ford or Dodge that Chevy even had an add campaine that claimed "Rides like a car! Works like a truck!".

Re: The Diffference between the 67-72 Chevy Trucks

this is a great thread
a little knowledge to add
some 67's and 68's didnt not have the dimple in the frame to acomodate for powersteering
and a correction
the ignition bezel changed slightly midyear 68, early production 68's still had the older ignition

Re: The Diffference between the 67-72 Chevy Trucks

1967-1969 K series trucks used the closed knuckle Dana 44 with drum brakes.

1970 K series trucks switched to the open knuckle Dana 44 with drum brakes.

1971-1972 K series trucks had the open knuckle Dana 44 with disk brakes.

It has been my observation that the manual shift 1967-1969 K10's and K20 had the Rockwell T221 transfer case while the 1969 K5 would have had the NP205 or Dana 20 transfer case. I believe the Dana 20 was never offered in any K10 or K20, just K5's.

I also believe the SM420 was used in the 1967 trucks but from 1968 to 1972 the SM465 was the manual option.
