66 SPID sticker language - share and learn!

So far that`s the information that we`ve found. The two letters can change with every production year. The RPO `Regular Production Order indicated what was asked for and the two letters informed the guy on the assembly line to put the correct matching parts. For instance a 292 motor for a 4 speed had different ECL than a Powerglide . The assembly line must have had engines set up with clutch assemblies as well as flexplates for Automatics. I still guessing at this point.

Major props Cortcomp, Aerotruk63, 60-66, and ALL you guys that are piecing together this complex puzzle. The Corvette guys are all about this type of research and have enjoyed a thorough understanding of nearly every aspect of their cars for many years, so I think it's great we are getting started on it too.
Keep it up boys, you really are breaking ground here!

Sorry to be joining late -

I've been building cars in GM assembly plants for 34 years, as a production supervisor, in Product Engineering and (for the last 14 years) in new product launch, and, based on my experience.....


....you are correct.



I don't have much time to write long sweeping narratives but I would be happy to answer any specfic questions you guys might have.

A couple additional comments -

a) I learned something new from this thread; I didn't realize those additional characters beyond the three space RPO code actually meant something. By they time I started in the '"73 and beyond" those had been reduced to mere dummy characters as placeholders. Now I see why they were there in the first place.

b) My professional expertise is in full size truck engineering and assembly, starting in 1979. My historical focus is the Pontiac Michigan assembly center of the mid 1960's.

If you have some time to do some general reading I would recommend these links:

This is specific to Camaros, but applies to all GM assembly plants in general
http://www.camaros.org/assemblyprocess.shtml#chev

This is more related to '73-'87, pictures with some insightful commentary:
http://www.73-87.com/7387info/Assembly%20Line.htm

The definitive overview of Pontiac passenger car assembly in the mid 60's ("Made in Pontiac" series; 5 parts):
http://wildaboutcarsonline.com/cgi-b...=9990401240631

This will give you a basic overview of how the cars/trucks were assembled, and therefore what the requirements were as far as receiving the RPO information, how that was disseminated through the plant to help facilitate the build, and how the parts needed to be configured to accomplish that.

I'll try to take some time and read through the previous 3 pages to see if I can learn something else or perhaps share some insights.
