'78 T/A fender tag decoding help
« on: April 04, 2019, 01:34:10 PM »
Hey all, I'd really appreciate it if someone could decode this fender tag on my 1978 Trans Am.  Owner said it was all original Martinique blue and light blue interior but I have evidence to suggest otherwise.

Thanks for any help

78 model year (st78), built week 3 January (01C), Its kinda confusing to me but I think the paint code is the 24U, which is Martinique blue, no idea what the U is. I think the L is for assembly plant (may be Lourdstown, Ohio?) I think the tr-248 is a trim number but no idea what that number means. Some of the info is for division series, body style and corporation type stuff. Im sure someone will fill in the blanks as there are those with far more knowledge on these things than myself.

L and U stands for lower and upper.

24B trim is blue velour.

The W's are for "water" to denote that it was painted with waterborne lacquer.

01C is the third week of January.

The assembly plant, L, is Van Nuys, California.  They did not make Firebirds at Lordstown in 1978.  I don't know what letter Lordstown was, but it's funny that it wasn't L, now that you mention that.  The Waterborne lacquer was used at Van Nuys but they did not use it at Norwood.

AussieTA, may I ask where did you get this information? Is it only specific to 1978 models? I've seen heaps of decoders but I don't think I've seen one that specific/comprehensive, "3 for power windows" "U for blue steering column"? I've never seen those ones before.

most of that came out of my memory
i did have to look up what the u was as i have B. black steer column
the van nuys cowl plates are hard to find info on and are different to norwood plates
i have lots of books and have been decoding the van nuys cowl plate since i bought my ta 23 years ago

And FWIW anybody can write a decoder on the internet, and then whatever mistakes are in that, they get copied all over the internet.  If you go to a car show thought you can look at 50 of them and you can figure out some of the extra stuff.

Every year is different.  Bank on that.  PLus, in 78, Norwood and Van Nuys are very much different in that one year.  There are some areas of consistency, and that is mainly how they did the date code and the paint and the interior colors.

I didn't think that they made f body's at Lourdstown ! At least the later cars. Since I have been documenting the Y89's I have noticed a difference in the van nuys and Norwood cowell tags, the VN tags have less info.

They made Firebirds at Lordstown in the 60's.  I am not sure when they stopped.

i believe this is correct for 1976 1977 and 1978 van nuys builds
i suspect where you have "U" is going to match the "Big 4" on the build sheet so yours would be 24X Big 4 Blue
but i cant confirm this, it is just my hypothesis
i would need some van nuys, dual colored interiors to support this

I just realized a 78 trans am can’t have a blue steering column.  If U is blue then i would agree it’s really talking about the “big 4” items.

Well-spotted, correct, that's a secondary code but not steering column. My black column Formula has T for tan, likewise couldn't get a Tan column.
I have also seen that letter reference column colour on a few online decoders. Doesn't mean they are all wrong, or all right, it could be different year to year and between factories.

i have seen that position on cowl plate decoded to be steering wheel, and steering column
but after more info it appears to be secondary interior color, big 4 on build sheet
comprising of kick panels, rear parcel shelf, console, dash pad, carpet
i will edit original response

It's still the same for 78, those items were black on Formula and TA, except Y88.

so it would appear column is incorrect and steering wheel may be correct
i will edit original response

This is the thing I have sample of the same year 1978 T/A with almost exact Cowl Tag color 24 and have "U" on the third line after week assembly this means
U = BLUE SECONDARY INTERIOR COLOR also in the buildsheet in BOX 106 = COL BLU =  COLOR BLUE SECONDARY INTERIOR COLOR
To Avoid confusions they use the last letter from the build sheet 'U" instead of the "B" is used for BLACK SECONDARY INTERIOR COLOR.
The steering column and the Steering Wheel is Black.
