SPID help "S" St. Louis plant - The 1947 - Present Chevrolet & GMC Truck Message Board Network

SS Tim · 12-03-2012, 07:23 PM

Having problems nailing down some information and need some help.
Many plants stopped using the RPO suffix codes on the later production trucks. However some plants continued to use them. Now I know that St.Louis switched to numbers from letters between '71 and '72. What I am trying to nail down is did this happen during the summer of 1971 MY change over, was it earlier or even later? Does anyone have a known original '71 "S" SPID with number suffixes? Does anyone have a known original '72 "S" SPID with letter suffixes?

Also I have a format question as well. So anyone who has an early '72 SPID from "S" St.Louis they will share, I would really like to see it. Ranges from 100001-110001 are best. For those who want to help but prefer not to post a VIN or SPID here is a short term address. Or if you have my normal email please feel free to use that as well.

Sorry, Here is a picture to clarify.

Tim, I have a few, 1S or 2S, SPIDS in my collection. They all have long code. The sequence numbers are 1,5,6,8, as GMC's were built there and they had two assy. lines. I can only send one or two in my email cause of settings I won't change. So I guess call me or I can send you a disk snail mail.

I will check mine when I get home late tonight. Most of mine are Fremont SPIDS, but I had Chipflyer duplicate my 72 Cheyenne SPID (before I sold the truck), and it was a St. Louis truck.

Tim I don't have any 71 labels in my collection with numbers (suffix) but I do have some 72 labels that you are looking for.

I have never had much luck trying to nail down specifics about plants or years when dealing with the labels. They certainly are interesting. I like to tell people you can never say "they always" or "they never" when discussing SPIDS. Always good info and a fun topic!

Thanks for the replies so far. Bruceman1968 & Chipflyer the provided SPIDs really helped to confirm just how inconsistant the early '72 SPIDs from St.Louis were. More are welcome of course from anyone.

**Bill72** · 12-04-2012, 01:29 AM

72 numbers not letters.

ChevLoRay · 12-04-2012, 12:17 PM

In looking at my book, the one used by dealerships to order new trucks, those prefixes and suffixes are not used. For instance, G60; U63, etc. It seems I read on here once that those other letters/numbers may have been applicable to a shift, or a line or ???

If it mattered, we might see a Z71 on the side of a 4WD that read, "1Z71AA".

Tim
I looked at the spid's last night. I have 2 72's from St.L
One is CCE242S17 and the other is CCE142S12 and both use nubers after the RPO code. I was surprised the rest of them I have are different plants as are the trucks I have with the exception of my C-30 which is CCE332S17 and it also has numbers after the RPO #.
Hope this helps.

SS Tim · 12-08-2012, 12:33 AM

Thanks for looking Tim. If any of them (...S2...) are below 110,000 could you please send a picture of it to me?
