Re: Blazer SPID thread?
 

Here is the SPID to my 72 Blazer. Factory 2wd. Can someone tell me exactly what the California Assembly and California Processing options consisted of? I know that it was something that vehicles that were destined for California had to have but what was it exactly? I guess that means my Blazer was sold originally in California? I ended up getting it from a board member in Louisiana who found it in Central Georgia. That is all the history about it I have though.

Nice blazer evan. Highly optioned. How's the interior. Being a z84 truck I always like seeing the insides

Thank you for the compliments!! I wish it had the plaid highlander (that's the z84 right?)seats still in it but looks like the previous owner/owners recovered or got some different seats. These are a couple pics of the first night I got it about a year and a half ago

Here is mine seems to open some questions for me.
I dont see the CST listed like on some others.
Is mine pretending to be a CST? PG :waah:

Re: Blazer SPID thread?
 

I believe what makes it a custom is the Cheyenne equipment package. You have a nice custom truck!

Re: Blazer SPID thread?
 

Correct, the RPO Z84 Cheyenne Equipment line on the SPID is the CST package. No worries there.

Re: Blazer SPID thread?
 

Close, RPO Z84 was the CST trim package. Highlanders were an upgrade of the Z84 adding the plaid cloth and special trim combintation. So since you also have the trim code 677, your Blazer was a factory blue plaid Highlander.

Re: Blazer SPID thread?
 

Basically it amounts to an emission test and an air pump. The heavier trucks so ordered were only certified as meeting California's emissions regs. But the C10s required an actual individual production line emission test.

While it suggests your truck was sold new in California it may have be sold in a bordering state as well. Many dealers whose sales areas would cross state lines ordered stock units with the emission package to maximize sales potential.

How about a black 72 Blazer w black interior? http://www.ebay.com/itm/Chevrolet-Bl...3D281700314649

Re: Blazer SPID thread?
 

locking hubs not on this one, another thing, seems a lot of blazers/jimmys had factory skid plates.

Re: Blazer SPID thread?
 

Thank you SS Tim for shedding some light on what my California Processing "Option" means.

Base model - good documentation pics and interesting SPID

Re: Blazer SPID thread?
 

Here is mine. 72 2wd.... not allot of options. Never realized I would have spid envy

Re: Blazer SPID thread?
 

Sorry. Other pic didn't load. Po replaced the parchment with black

Re: Blazer SPID thread?
 

I wish I had a picture of my old 72's SPID... It was loaded but I don't recall ever reconciling its equipment with the sticker.
My recently acquired '69 CST doesn't have the right glovebox door so no SPID for me. It's a very interesting thread though and I've enjoyed it.

I do have a few questions after reading here though.

*I assumed at first that "removable top" and "auxiliary top" would be the same thing, maybe just from different plants- except I see that they have different codes.

*Does there seem to be any order to the way rpos are listed? It won't be "real" but I'd like to do my best to replicate a SPID with the options/colors that I see on mine

*I don't recall seeing a SPID listing cruise control. Was that an original option on 69-72s?

*I had at least one more question but I'll have to come back and edit it---

Thanks guys- Greg

Re: Blazer SPID thread?
 

The two aux. top codes to look for are Z58 White and Z59 Black not much else matters, St Louis had some real issues with SPID content, constistency and format.

Getting a reasonably accurate replacement SPID made is a matter of knowing what you have, what to look for in the vehicle's original build and referencing known SPIDs from the same plant and serial range. To me a guesstimated SPID based on about the level of verification most people would do for a for sale ad is worse than no SPID at all.

The only listing I show for factory installed cruise RPO K30 is for a 70 C/10 (4x2 Blazer) with a 350. While there were dealer cruise kits they would not be reflected on the SPID.

If you have another Blazer related SPID question, don't edit but simply post a new reply. Edits don't trigger a subscription notification.

Re: Blazer SPID thread?
 

Thanks SS Tim- looking back to post 90 (and others) there's an auxiliary top listed and it has a different rpo number. That's the type I was asking about. I still assume it's just a plant difference because I've not seen a different top---

Re: Blazer SPID thread?
 

http://67-72chevytrucks.com/vboard/s...9&postcount=90

Its a Z58 White top as expected. Go by the RPO number first, then worry about the decription. In this case its the same option different description.

If you go to:
http://67-72chevytrucks.com/vboard/s...&postcount=216

This is a very early build 72 from St Louis.
It also has the Z58 RPO code for a white top without description and on another line CB8 "REMOVABLE TOP" which is actually the build conversion code. It like several other lines on this early 72 SPID are generally not listed and are found only on the actual build sheet. St Louis again had a lot of issues with SPIDs.

Also if you right click on a post number, it will give you a single post thread link code that is easy to paste into a reply when refering to a specific example.

Re: Blazer SPID thread?
 

So is there a different code between the single wall top and the double wall top?

Is there a way you can tell the difference from the SPID?

Re: Blazer SPID thread?
 

Currently on eBay...quite a schizophrenic SPID. Must've been on a Friday or something.

Re: Blazer SPID thread?
 

LOL! That one gets my vole for the oddest one yet - thanks for posting Brad.

Re: Blazer SPID thread?
 

It's neat not only for the unlabeled codes or the random codes, but also for the BX2 and the A50 which I think should technically be covered by the Z84.

Edit---also by the book, I think all CSTs should have come with a spare tire cover.

Double edit--another one I missed...how about the CB8 and Z58

Re: Blazer SPID thread?
 

Man that truck had everything. Except had z84 package and ordered black vinyl seats. Should be highlander with that. Some of the blanks I'm wondering about though.

Re: Blazer SPID thread?
 

CKE182F100563 is the listed VIN.

Nothing sinister or really unusual actually. Go back to posts 219-222 for a similar St. Louis example. Its really just a case of too much information common during SPID format changes.

Being the 563rd truck off of the 72 Flint line I am surprised its even that good. There were a lot of issues getting the correct RPO suffix codes during the change over from letters to numbers for the 72 MY.

It was what it codes.
K5 Hugger Orange with Black CST trim and a White top.

BTW Those RM1 codes with the blank descriptions are H78-15/B
On-Off Road Bias Belted tires.

CSTs ordered with a hard top included a spare tire cover. So most but not all CSTs had tire covers as shipped.

Re: Blazer SPID thread?
 

To clear things up this is from GM dated January, 1972

"New Removable Top Assembly (RPO CC3) 1972 Blazer

A new (simplified construction) top is being offered to supplement the currently available (RPO CB8) top for Blazer models. The new top (RPO CC3) is a single skin design with three exposed interior roof rib reinforcements running from side to side, whereas the RPO CB8 top is a double skin design with inner roof panel lines running front to rear. Part numbers for the two tops are as follows:

RPO---Part No.--Color
CB8--6262051---Black
-------6262052--White

CC3--6271845---Black
-------6271846--White


Mounting of the new top differs from the earlier style in that attachment to the box is accomplished through floating anchors contained in the box sides (Fig.1). The top is then bolted from above making trim panel removal unnecessary.

New parts contained in the RPO CC3 top are:

* Side door glass weatherstrip and retainer (providing an adjustable weatherstrip feature).

* Thinner (1/8 inch) side glass and weatherstrip.

* Top to box weatherstrip.

* Seal and metal retainer around lift gate hinges.

* Top to box side molding and chrome plated hold-down bolts.

The lift gate and attaching parts, header weatherstrio, and header attachments are common to both tops."


Unfortunately unless you have a build (broadcast) sheet or one of the atypical SPID as mention in earlier posting you will not see the CB8 OR CC3 codes. Generally they are found only on the build (broadcast) sheet. There they indicate the conversion of the vehicle to a removable hard top. Where the generally seen SPID codes Z58 (White) and Z59 (Black) really only indicate the color and confirm a factory hardtop installation.

Re: Blazer SPID thread?
 

Wow Tim...fantastic info as always. Thanks for being the guru.
