I was looking for information on the web about Chevelles (as usual) and came across this really cool site. I think it will be very useful to all especially with 1970 Chevelles looking to decode their Cowl Tags.

Thinks 13667 is a V8 - body plates don't designate 6 cyl or 8 cyl engine status; doesn't recognize any paint color or convertible top color for upper body, only vinyl tops; says "A" is a white vinyl top on a convertible; has block for A51 (bucket) or A52 (bench) when 70 tags don't use those designators - A51 and A52 weren't used until 1972. :noway:

68-71 VIN decoder isn't much better, no checks for invalid entries. An invalid VIN like 138800K123456 decodes to a 70 Concours/Monte Carlo, 8 cylinder 2-dr pickup (body plate decoder also allows 13880 entry). :noway:

All-in-all, needs some serious error trapping, style checking, and knowledge of 1970 body plate information.

I like my site better. :)

Be careful Dennis. Chevelle stuff is Dale's site. Most things on there are correct, But if you find an error just let Dale know and he will fix it.
Look again at 1970 bodyplate/vin decoding. It states. MODEL 135-13667 ~ 2-DOOR CONVERTIBLE, 5-PASSENGER
No mention of 6 or 8.

Chevellestuff.com is indeed correct. What you copied was the VIN section. The Fisher Body plate section above that reads:

Typical 1970 Fisher Body plate breakdown. Some assembly plants have more information on their plates than others and some have information on different lines. Please check the individual assembly plants for specifics.
Line 1: The first number on line one is the year of production followed by division/series/body style, assembly plant, and the Fisher Body unit number used for production purposes.

SERIES/MODEL IDENTIFICATION (for trim level purposes only, not for engine type identification)
NOMAD STATION WAGON 131-13200
MODEL 131-13236 ~ 4-DOOR STATION WAGON

CHEVELLE (STANDARD) 133-13400
MODEL 133-13437 ~ 2-DOOR SPORT COUPE, 5-PASSENGER
MODEL 133-13469 ~ 4-DOOR SEDAN, 6-PASSENGER

MALIBU SERIES 135-13600
MODEL 135-13669 ~ 4-DOOR SEDAN, 6-PASSENGER
MODEL 135-13639 ~ 4-DOOR SPORT SEDAN, 6-PASSENGER
MODEL 135-13637 ~ 2-DOOR SPORT COUPE, 5-PASSENGER
MODEL 135-13667 ~ 2-DOOR CONVERTIBLE, 5-PASSENGER
MODEL 135-13680 ~ 2-DOOR SEDAN PICKUP, 5-PASSENGER

GREENBRIER/CONCOURS STATION WAGONS 133-134-135-136-13800
MODEL 133-13435 ~ GREENBRIER 4-DOOR STATION WAGON, 2-SEAT
MODEL 13446 ~ GREENBRIER 4-DOOR STATION WAGON, 3-SEAT
MODEL 135-13636 ~ CONCOURS 4-DOOR STATION WAGON, 2-SEAT
MODEL 13646 ~ CONCOURS 4-DOOR STATION WAGON, 3-SEAT
MODEL 13836 ~ CONCOURS ESTATE 4-DOOR STATION WAGON, 2-SEAT
MODEL 13846 ~ CONCOURS ESTATE 4-DOOR STATION WAGON, 3-SEAT

I applaud the gentleman's effort and while I doubt anyone would enter a body style or VIN of 13880 it still leaves open the possibility. Not recognizing upper paint colors and assuming all tops are vinyl tops, even on convertilbes, is problematic. That and allowing (apparently requiring) A51 or A52 as a seat type is incorrect as stated. Those codes didn't appear on Fisher Body plates until 1972. On 13637 Malibu sport coupes, Atlanta also had B80 and B90 coded after the interior trim.

I did a couple more tests and found if I enter the following into the Fisher Body plate decoder:
* Entering BL 01892 (correct with space) the assembly plant, Van Nuys, isn't recognized. If I don't put a space between the "L" and the "0" (BL01892 - incorrect), the 01892 is truncated to 1892. I couldn't get any letters to come up with Van Nuys assembly plant; tried VN, BL, L, LA, etc. - nothing until I realized the other plants were using three letters; tried LOS before it came up with Los Angeles (which really should be Van Nuys).
* Entering BT10361 (which is correct without the space) again no assembly plant is identified and the number is truncated to 0361. With a space (which is incorrect), still no plant is identified but the number is correctly displayed as 10361. ARL (incorrect) is required to get Arlington to display as the assembly plant.
* Entering A 14817 (correct with the space) again doesn't identify the plant as Atlanta and number is truncated to 4817. ATL (incorrect) is required for Atlanta.
* Entering B754688 (correct without space) doesn't identify the plant as Baltimore and truncated the ID number to 4688. BAL (incorrect) is required for Baltimore.
* Entering FL2105449 (correct without space) doesn't identify the plant as Flint but does display all 6 of the ID number. FLI (incorrect) is required for Flint.
* Kansas City is the only plant it get correct. KAN508765 does identify Kansas City and ID number is displayed in full. One side note, if it's going to identify the Leeds plant at Kansas City it should identify the Lakewood plant for Atlanta.

So, other than getting the year correct, recognizing ONLY the Kansas City plant as per the body plate (serious flaw IMO), and recognizing all the lower body colors (and lower body colors only), trim code wise it identified 18 correct codes but missed 24 codes as not in the database.

As it stands, unless you have a Kansas City built car with a vinyl top and selected interior trim, a user is out of luck even entering correct data. Nice effort but it needs work. :thumbsup:
