SPID Line Items Question

[thump426er]

Hi there, have a couple questions for you all from 2 trucks SPID's and what they are.

1968 swb 2wd auto column shift (now 700r but not sure what was in it originally):

- option #04Z62EA Custom C&C Equip
- option #04MIOAK Overdrive Trans (I didnt realize there was an overdrive auto trans back then??)

1972 K20 two tone paint:

- option #400188 Special Paint (the SPID doesnt say color in any of the line items, just this "special paint" item, does this just reference that it is a two tone paint job?)

Thanks and appreciate any input you may have.

This sight should help you with all your specific trucks codes...

The overdrive transmission was a 3spd manual +1 overdrive gear. It engaged using a cable with a pull that mounted under the dash.

Option Z62 was "Custom" comfort & convenience

Thanks to both of you, that helps, and,,, looks like I have some reading ahead of me. Very useful info in there for sure..

Like Tim said the Z62 is a trim package and there should be "Custom" badges on the doors near the top center.

The M10 was a three-speed manual trans (column shift) with an overdrive element added to it. It was electrical in operation using solenoids, relays and ignition interruption to upshift at part throttle. The cable control was actually a defeat funtion to lock out the unit when loaded.

"Special Paint" means exactly that, other than standard production. It could be used for non-production colors like EZ Haul rental green or more often production colors in a non-standard arrangement like this truck in a reverse special two-tone of ochre and white. There is no way to determine the color or arrangement just from the RPO code that I am aware of.

I am in total agreement with what has been posted thus far; the only thing I would add is you will notice the actual RPO code resides in the middle of the digits you posted; ie, "Z62" and M10" are the legit RPOs.

The preceding and subtended characters are "dummy" characters, placeholders, if you will.

At one time they represented a "functional name address", sort of a sub-RPO, but by the time I came along they didn't really mean anything, and can be disregarded when researching your option content. This was implied above but had not yet been stated explicitly.

Thats very interesting. So here is a picture of my 72, guessing this is ochre with the white. However this seems "normal" to me. My When I bought this maybe 4 years ago I bought it from the original owners son. He said it had never been painted or in any accidents, only had Warn hubs thrown on and a spray in liner. Garage kept its entire life apparently and looked that way when I first saw it. There doesn't appear to be any evidence of painting etc. Is there something i should look for that might be indicative of a "special" paint? Or is this pattern (which seems quite common for 72) considered special. Here is the SPID for my 72, is there another item that I'm not thinking might reference the paint etc, seems obvious to me but just in case.
Thanks again, great info from you guys.
Never knew there was an overdrive which you actuate under the dash.

[SS Tim]

From that picture its hard to tell what the color might be. To me it looks browner than ochre.
The ochre and white I posted up is a code 4001WC vs your 4001BB. There is undoubtedly something in the exception codes (suffix letters) that I may eventually determine by say 2072.
If your truck is a "Z" Fremont truck then look about behind the seat for the build sheet as I'd really like to see that clearly.
Getting to the bottom of what you have may be difficult if even possible. It could have been as simple as body color wheels. P/M an email if you want to explore this.

On the overdrive it was a pull to deactivate otherwise it automatically shifted in and out of O/D relative to throttle position.

It does appear to be darker that Ochre.

I always wondered what the dummy characters were for and why some SPIDs have them and some don't. Thanks for posting this Keith, you are a great asset to this forum ( so are you Tim ).

While you are correct in that they can for all intents be disregarded for general research. Also that, per you, they were not in use thus "Dummy Characters" by the later '70s.
But during the 67-72 period the suffix letters/numbers were still in use, more so in the earlier than later years. They were used to denote a variation of the RPO code.
As an example in '68 the V37 Chrome Bumper _ _ _ was common to all applications and it was the suffix letters (and description) that denoted if it was an optional front AA, an optional rear or optional front and rear EA (shortbed fleetside).

its much darker I have the exat truck with the exat options but mine is orche with original paint and air mine also does not show wheel option its your brother

Looks like white below the trim, color only above the belt line and a white roof.

While that is possible, I blew the picture up the first time around and convinced myself then it is the bodycolor down there. However it is lightened a great deal by the snow reflection.

[thump426er]

Sorry, didn't pay attention the color below wasn't that visible. Here is a better side to show the color below.
The rear bumper was the usual checker plated top work bumper.
I'll dig around for the build sheet and post up once/if found. I'd like to know that color. I know this isnt the be all end all but this website for paint matching http://www.paintscratch.com/touch_up...let-Truck.html none of the colors really match the truck when I compare say inside the glovebox or interior where its never/less been sun affected.
