Cowl Tag Decode

Anyone care to help with this cowl tag?

VIN is 3G87H2Z102531 which decodes to a 72 Cutlass S Holiday Hardtop, with a 350 2 bbl, built in fremont according to the what I can find. I haven't had any luck with finding info for anthing else though.

Thanks ahead of time!!

First, your VIN of 3G87H2Z102531.


3 = GM division = Oldsmobile


G87 = Model series and body type = Cutlass S Hardtop Coupe (series 3687)


H = engine = 350ci 2bbl (L32) single exhaust


2 = model year = 1972


Z = assembly plant = Fremont, CA


102531 = plant sequential number (yours is a fairly early production car)


Next, the trim tag.


ST 72 = style/model year = 1972


33687: 3 = GM division = Oldsmobile; 36 = model series = Cutlass V8; 87 = body type = hardtop coupe


Z = assembly plant = Fremont, CA


00768 BDY = Fisher body number (completely unrelated to your VIN)


TR 954 = interior color = gold (cloth, perhaps?)


A52 = seat type = option code = conventional/split bench seat


53 53 PNT: 53 = lower body color = Saturn gold; the next 53 = upper body color = also Saturn gold


09C = time build code = September (09), third week of that month (C), 1971


Hope this helps!

Hey Randy,
Could you please decode my car. I'm trying to figure out colors.
The car is currently painted with Nordic Blue but I'm not sure if that's original.

Thanks,

Thank you!!

Seats are faded to look dirty white, but they do have cloth inserts, instead of being all vinyl.

Nordic Blue w/white convertible top, 983 Is a Green interior, that's unusual... a blue car with a green interior.

For Johnny Flames, this is what I come up with. FYI, you can do a search on this site for a web site that will also break down this info for you. Someone here did a wonderful job of putting it together and it works!


Here's what I came up with for your car:


ST 71 = style/model year = 1971


34267: 3 = GM division = Oldsmobile; 42 = model series = Cutlass Supreme; 67 = body type = convertible


LAN = assembly plant = Lansing, MI


206899 BDY = Fisher body number (no relation to your VIN at all)


TR 983 = interior color and front seat type = blue interior with a notch back bench seat (my book shows blue interior whereas 1969w3155 shows green, which indeed would be unusual!)


24 A PNT: 24 = lower body color = Nordic blue; A = convertible top color = white


09A = time build code = September (09), first week of that month (A), 1970.


My guess is that you probably have a low VIN number, too, something like 342671M10nnnn, where nnnn is a number in the 1000s or 2000s. Just guessing here, tho.

I think that my source is wrong, as it shows 992 972 983 as green, and blue as 993 & 973, I believe that the last digit is the indicator for interior colors, the 3 being correct for blue, no matter what the first two digits are (they indicate seat style and/or material). I looked at another source, which has poor info for the interior color, no numbers listed, just the name for '71, but other years the Blue interiors all numbers end in a 3. In the back of my book, it indeed shows 983 as blue.

My source shows 972, 952 and 932 as green interior, and 983, 943 and 933 as blue interior for the 1971 model year.

Yours is correct, I found another error in my book with another interior color. In the back of my book, on another page they are listed correctly.

Thanks 1969w3155! This one has Rallye Red. I wonder which of those colors is the most rare. Were they all the same upcharge?

Unfortunately no Olds records for these years are available , so numbers for cars built with any combination of options is unavailable. If someone here as a dealer spec & price guide, that may show the cost of the special order paints.

Now according to your great decoding skills and also this site: http://www.wmachineregistry.com/inde...total-by-month

, it appears that not only is this quite possibly a W30, but also one of the first few hundred off the assembly line. That is very special indeed.

Not sure on the color, have some work to do before I know if how bad it is. So far I've found the roof has been hacked and patched, and if full of bondo, as are the fenders. It needs a trunk floor trunk lid, and lower quarters. But the floor is rock solid..

Do you mean Broadcast Card? Build sheets are not usually found under the car seat. Is your car a Lansing build?

Has anyone else noticed the line spacing on the numbers on mine? Is it common to see a tag that is slightly shifted like this? All that I've seen have been straight across. But I'm assuming that this was some kind of manual punch process, so I guess it could be subject to some tolerance error depending on the operator.

Thanks guys and I apologize for "hijacking". I'm guessing someone had the car repainted another color it's a maroon color the top was the right color before I removed it to replace. I really appreciate the help!

I see that this is an old post. This is not the best picture but a vehicle I’m looking to purchase. Can someone see well enough to decode my cowl tag?

Yours will probably be shifted to a new post but here's my best shot at it.

ST72 = style/model year = 1972
34267: 3 = GM division = Oldsmobile; 42 = model series = Cutlass Supreme; 67 = body type = convertible
LAN = assembly plant = Lansing MI
247807 BDY = Fisher Body number (has no relationship to the VIN)
TR 977 = interior color = white
26 = body color = Viking blue
A = convertible top color = white
09D = time build code = September (09), fourth week of that month (D), 1970 (this is an early production car; gearing up for production of the next year's model car usually started in the middle of August of the previous year)
A65 = option code = notch back bench front seat

Good Morning Randy C. I was going back through some old threads and came across your reply. It brings up a question I have. You’re saying My vehicle (1972) was being built or built 4th week in “1970”? How did you gather that year from the Cowl tag?

I just don’t understand where someone gets 1970
Am I really missing the obvious??

This is a 1972 model year Olds as indicated by the ST72 at the upper left of the tag.

Exactly. Perhaps they were responding to the other cowl tag but specifically called out all of my paint color, interior color, seat type, etc but then also said it was an early 1970 build. That’s where I’m lost.

Yes, indeedee, a slip of the "essentially tremored" finger on the keyboard! The car is a 1972 model year; the build date is September (09), fourth week of that month (D), 1971.
