what year is my GMC 3/4 ton?

The bill of sale says 1966, the KS HP ran a national vin ck and it was last tagged as 65, the vin ck-ed as a 61 on stove bolt's vin buster site. A friend told me it had to be a 60-65 because it has leaf springs not coils. The HP guy said to give him a call if I can nail it down to the right year and he'd send in the right "attachment papers" to up date the antique title. So what have I got? (I know it's not a problem to tage it but I'd like to know) Thanks, budrow out

 

Pictures would help. The windshield and doors changed during this time. There is a wrap around windshield up to a certain point (like 63?) and a much flatter glass with angled doors after that.

 

Coil springs were also used up into the end of the 1972 series as well, depending on what you were running.

 

try looking through this thread and see if it helps you.

60-66 gmcs were all leaf spring, however they could be special ordered with coil springs.

also,if my vin thread dosen't help, go to the vin section of this gmc site: www.6066gmcguy.org/

 

If it has a "dog leg" windshield post, it's pre-'64. Also should have the two-bulge hood, the later ones had a smoother hood. Some '62-'63's had torsion bar front end.

 

a "what is it thread" with no pictures. lol

 

no pics AND no VIN. Also if there's a number stamped on the frame, on top on the drivers side frame rail in the engine compartment, let us know what that is. I think you'll find leafs on the back of GMC trucks after 65, also

 

The vin is 1502pf28052b, and here are some pics. Thanks for any help you can give. budrow out

 

hey BUDROW... i can tell you for sure it's not a 1960, and i can tell you for sure it's nota 1962. and can tell you for sure it's some where in between. i hope this helped! HA! call me POP...or the old FART!

 

64/5/6

1500 is a 3/4 ton. The 8 lug wheels are a giveaway to that fact too

looks like a 66, since the vin sequential number is above 25000

Probably no way to know for sure...they seem to have no year in the VIN, funny stuff there

 

GMC was funny that way. They didn't seem to think model year mattered.

 

Well, it didn't, as long as the truck did the job it was intended to. If it's all original, casting dates on the block and engine parts, or the trans case codes, might pin it down better.

 

My wife just told me she likes this old truck,I'm surprised, she wants me to paint it and keep it around for a work truck. I didn't tell her my fishing poles are already in the rt. side storage box. Thanks for all your help. Guess it don't mater what year it is as long as my wife and the state are happy.

 

here is what I deciphered from your vin, and my link...
1502pf28052b
15=1500 series
02=127 inch wheelbase
p=pontiac michigan assembly plant
f= year*** see info at bottom
28052= sequential serial #
b=GVW, which is 6001

*** the explanation of "F"
The series letter for 1964 to 1966 is "F". There was not any
more major changes for this body style. But there was a series letter "E" used on some
1965 trucks (have not seen any yet) & "D" used on all inline engined 1966 trucks. More
info has been found for "F" Series Trucks, GMC built truck in two plants from 1964 to
1966, the Pontiac Michigan plant & one of two plants in California, Oakland or Fremont.
If your trucks vin shows "HF" it was built in the Oakland California plant which GMC shut
down after the 1964 Model year, so all "HF" trucks are 1964. Production was moved to an
ALL NEW plant built in Fremont California for 1965, so "ZF" trucks are 1965 or 1966.

So here is a brake down of the series letters;
N = 1960-1961, J = 1962, G = 1963, F =1964-1966, E = 1965, D = 1966

The next group of numbers is the Serial number or unit built number, all series at all plants
started with Serial number 1001. For the 1966 year run, GMC started most series with Serial
number 10,001, but some series not used in 1965 started with 1001. I have found that GMC had
a lot of left over trucks from 1965 & they sold them NEW in 1966 as 1966 Models, this was
done to rid the dealers of any older trucks still on the lot to make way for the NEW body
Style coming in 1967. If you have a GMC "PF" or "ZF" series truck titled as a 1966, but the
Serial number is lower then 10,000, it mite really be a 1965 model year truck. One way to
tell is to check the engine for a spin-on oil filter, no spin-on filter, then it's a 1965.
GMC swithed to the spin-on oil filter for the 1966 model year on V6 powered trucks.
The last letter is GVW class.
A = 6000 lbs or less, B = 6001 to 10,000, C= 10,001 to 14,000

There was some overlap with the Series Letters - GMC just liked to confuse people I guess.
Conrad has a couple books that show that the "N" series started in 1960 & actually going
to 1966, the "J" series started in 1962 & went to 1966, the "G" series started in 1963 &
went to 1966, the "F" series started in 1964 & went to 1966. The "D" series was Used on all
1966 model with Inline 6 engines. So a "D" series is a true 1966 truck while a 1966 "F"
series is a continuation of when GMC started building the "F" series in 1964. Most of the
overlap in series letters is with BIG GMC TRUCKS like the Model 4000 & up. We haven't seen
a Model 1000-3000 "N" series past 1961, a "J" series other than a 1962, or a "G" series other
than a 1963 on what most folks call "Light Duty Trucks". Starting in the mid sixties is
when auto manufacturers started putting more emphasis on the year of production, rather
than the "series". It was common for Trucks to get titled for the year they sold instead
of the year they were built. My truck is a 1965 model, but it's title said 1966.
hope this helps​

^ this above info is from www.6066gmcguy.org/

 

Factory backup lights and 4way flashers would indicate 1966 on a Chevy anyways.

 

also.. your pic of the front shows the one year only 66 gmc square grille letters

- Iwill hazard a guess that yours is a 66 that was sold during october to december of '65, thus the 65 title on the 66 truck

 

good point, and it probably had factory seat belts too. early safety stuff that was installed on all 66 vehicles, afaik

 

The truck is a '66, and what was said above about the registered year being the year it was first sold vs the build date year, that's probably the answer to your question - a '66 truck sold new from Sept - Dec 1965.

 

I would have to say those tool boxes look better than the regular stepside fenders on a long stepside bed.

 

Thanks for all the info. We're going to slick it up and keep it. It has power steering and brakes and drives real nice. Thanks again. budrow out
