F-Code...not X-Code
« on: December 07, 2009, 09:19:50 AM »
There's not much info in the books about the LOS and VN cowl tags.

Here's a different code on the Cowl Tag.  Instead of an X-Code it's an F-Code...  :)  It appears to be a Fisher Body plant assembly number that is typically located above the "BODY" in the upper right hand corner on the '68 tag.  I've also seen a D096 stamped in this area on a '69 VN cowl tag.  It appears to be a LOS and VN deal not talked about.

From here:

"Field b (LOS vs NOR)
LOS - Fisher Body body scheduling code
The LOS (Los Angeles/Van Nuys) body scheduling code is a letter followed by one to three digits, e.g., F103. Based on data analysis only (there is no GM documentation yet available that describes this code) - but with consistent application to thousands of datapoints - CRG believes the code was used by LOS Fisher Body (and other plants that built multiple carlines) to aid in scheduling the body build order.

The letter indicates the approximate production day of the month for the start of the assembly of each vehicle body. It began with letter "A" on the first day of the month of the Fisher production calendar, incremented at the start of each additional production day to the next alphabetic letter, and was reset to letter "A" at the start of the next production month. (Note that the Fisher production calendar is known to differ slightly from the calendar month, and we also do not yet know exactly how the Fisher production calendar related to the Chevrolet monthly production reporting calendar.)

The one-to-three digit sequence number that follows the letter was reset to 1 at the start of each production day and was incremented serially with each body built by the factory as the day progressed. Data analysis indicates that the sequence number at the LOS plant was assigned regardless of model or body type. By this we mean that Camaros and full-size passenger cars both incremented the same sequence counter. The unit counter was reset to 1 the next day as the day-of-the-month code letter incremented to the next letter. In the example, F103 would indicate the sixth day of production for a given month and the 103rd body started on that sixth day of production. "

This site helped me with that very same issue a few years ago.   My car is a L.A. built 69 with the same type of tag,  except my code begins with X,  as in X278!   I questioned what type of Trim package that was before learning what it really represented here on this Forum.

The transition from LOS to VN is also discussed on that same page.

Lots of those LA tags around the various sites with the unique codes as mentioned by the Kurt and Mark. Funny deal is mine just happened to be X164, so some folks think its a mistake to have an X code on an LA built car,... nope. X is 24th day of the month, and my car was the 164th that day to go down the line.
 This site and have always known about the LA codes, so they are not exotic at all. Just some folks jump to conclusions before they research it. Enjoy the LA car, its around 3 weeks newer than mine.
