What denotes the C/10 vs Custom/10 emblems

[special-K]

SPID is the option sheet on the glovebox door.I never called it that until I realized I was about the only one here that called it the VIN-specs sheet,which is what all my longtimer buddies always called it.I`m took GM books refer to it as a SPID(special parts ID?).
I`d guess yours is a CustomDeluxe,based on the rubber mat and trimmed glass.You prolly don`t have a headliner and the door panels have chrome trim around scrolled pattern.If you have the SPID still there,it may say full foam seat.Your seat would have been covered with a cloth insert that that is same color as vinyl with a lacey pattern.The dash knobs and pedals have trim.
I see you have "Custom" door panels.I wonder what`s original and what`s changed.I don`t know why someone would change the door panels.

mine is a 1970 c10 that has been in the family since it was new and it has custom 10 on the frt fenders along with the 8/350 emblem .

So I see that this was all settled back in 07 lol But I have what I believe and have been told is a 70 c/10 with custom badges on the door and c/10 on the fender. Are the custom badges wrong? Or did I not read fully?

[too much stuff]

The custom emblem on your door is 67-68. The fender emblem looks correct.

My 70 custom 10 with its orignal fender emblems.

Ethan, your truck is a base model (i.e. no trim RPO on your SPID) - too much stuff is correct, the Custom emblem was added somewhere along the way and your fenders emblems are correct. By comparison, Bill's 70 is a Z62 option, the middle trim level - one step up from the base model and one step below the Z84 CST option.

Alright so I just realized I had this picture. Does this mean it is a 69 built for the 70 sales year?

Correct. Looks like someone added the 67-68 emblem to your original door. It was built in 69 but it is a 70 model.
New models usually came out in sept.

[FleetsidePaul]

A little off topic but why do people always scribble on the SPID?

They obviously have something to write on or they wouldn't need a pen?

You are correct.
It’s all about the Level of trim package.
68-70
The C-10 is the Base Model, many times they were Fleet Trucks.
No frills trucks used for work.
Black rubber mats, no PS/PB, Manual trans, 6cyl,, in other words, very low optioned.
custom 10 is the “Mid Level” of Options, which many times are the the Truck that were ordered with options the the new owner ordered (like mine).
Back then you could order just about any option you wanted, and that why there are so really unusual optioned trucks out there.
Top of the line was the Custom Sport Truck (CST), but again, these trucks have a myriad of options based on how they were ordered.
71-72, Chevrolet kept the C-10 for Fleet Trucks,, but the Mid and Higher level truck had the Cheyenne/Cheyenne Super Badging

Both of those guys were incorrect. Read on and you will see I set things straight back in '07

Chevrolet must be incorrect too, my truck has had no work done on it and that is how it came from the factory.

Yes.
C/10: generally denotes Lower optioned, mostly Fleet Vehicles when ordered new.
Custom/10: mid optioned trucks usually ordered to have a few “Comfort/Conveniency options, 71-72 known as Cheyenne
CST/10: Top of the line trucks as far as options go, known as Cheyenne Super 71-72
I’m not “The All Knowing” expert on this so if anyone can add to it

[jocko]

As far as trim levels go, 67-70 CST is equivalent to 71-72 Cheyenne (and shares the Z84 RPO code). Cheyenne Super was a new, additional trim level added mid-71 with a new RPO code (YE9). So, while both CST and Cheyenne Super were top of the line trim levels "in their times," they weren't equivalent trim levels, per se. The CST evolved to become the "next-to-highest" trim level as of mid-71 and continued to live on into the square years as the Z84 RPO.

Mine has them: 70 Custom/10

Maybe the 70 year in question? C10 on 69 and previous is no question. On 71-72 it would display Custom 10/20/30 on fender ahead of door, base model. Deluxe would be displayed below that if equipped (like my truck). The CI would be displayed below the front marker. Cheyenne 10/20/30 would be displayed if equipped and super would be displayed under that replacing the deluxe if equipped. A Cheyenne deluxe was not available. I think in 70 and possibly 71 the trucks had CST on the SPID while badged as custom deluxe. The upgraded trim level.

Right. In mid-71 Chevy went from three trim levels to four by adding the Cheyenne Super which was a whole new RPO code

No designation by emblem on 67/68 other than series, 10/20/30

69/70 used trim level badges which were C for base, Custom for mid, and CST for top level

71/72 trim levels were Custom for base, Custom Deluxe for mid, Cheyenne for top, until Cheyenne Super came out in mid-71. First year for four trim levels

In '70 there was no Custom Deluxe. In 67-70 the Custom was equivalent to the 71/72 Custom Deluxe...same RPO

Many '71s had CST listed on the SPID but those trucks were actually Cheyennes, the 71/72 equivalent to the CST...same RPO

You are misunderstanding something here. no one has questioned the authenticity of your truck. I suggest you go back 17 years in this thread where all this was corrected and laid out accurately, as I suggested before. Back then this place was far less educated than it is now

Base trim trucks were very common among private owners, not mostly fleets. C/10 and Custom/10 in 71/72 absolutely denote the base trim models. But one could have more options than a CST/Cheyenne/Cheyenne Super

Custom 10 (67-70) and Custom Deluxe 10 (71/72) were mid level trim models which automatically meant Comfort & Convenience pkg. Both had same RPO

CST/10 (67-70) and Cheyenne (71/72) were top trim levels, but again, had nothing to do with options, only included features. You could have a '72 Custom/10 with more options than the higher trim levels. But you wouldn't have trimmed windows, color coordinated mat or carpet and other features included in the higher trim levels.

Cheyenne Super is the fourth trim level, now the highest, that came along mid-year '71 and it adds only a few features to the Cheyenne...seat material, woodgrain dash, upper trim, and trimmed tailgate handle

Trying to solve a mystery of the emblems on my truck. It is a 1970 C/10 with the correct C/10 emblems on the fenders but it has a Chevrolet Custom emblem on the glove box door. It's my understanding that the 69-70 C/10 trucks would not have had an emblem on the glove box and that the Chevrolet Custom glove box emblem would've been installed on the Custom/10, 20, etc. trucks. I have seen only one other example with this combination of emblems. Unfortunately for me, the member didn't post a pic of the SPID. It's my thought this may have been something being done by a particular plant. Wondering if any of you have a 69-70 C/10 with the same glove box emblem.

Here are a couple pics of my truck showing the fender and glove box emblems.





Here are a couple pics of Becker67's 1969 C/10 with the same combination of emblems. His truck appears to be in mostly original condition, down to the original front grille and white bumpers which would be correct for the C/10 trim level.

[special-K]

I can't explain that one. It is certainly an exception. That emblem belongs on Custom/10 glovebox doors and a C/10 should have a plain one. In 71/72, when they did do things different from 69/70, only the Cheyenne Super got an emblem on the glovebox door

Is your 1970 an early production? 1969 Customs did not get the Custom/10 front fender emblems-only the glove box door and on the SPID. Sounds like those emblems came along later in the 1970 model year.

[cericd]

Here's my SPID and blue "date of manufacture" sticker.



According to the blue sticker my truck was built 11/69.

[1970cstblazer]

I don't see RPO Z62 on the SPID
