seatbelt code?

I have rear seat belts that have the following code: 10A72
Can someone please decode for me?
Thanks
Tim

 

Tim,

I'm not 100% sure, but that looks like model year 1972 (72),
10th month (10), first week (A), so 1st week of October 1972

But if this seatbelt is in your 1972 model year Skylark, it's a bit strange, because that model year ended on September 20th 1972.....

 

perhaps they were replaced or the car was built without the belts due to a shotrage.
the car would have been unshipped until belts were installed .

 

Tim,
Try this decode,

(10A72)
(10th week, A-body, 1972)

Which would make the production date of the car right around the last week of March to the beginning of April of 1972.

I don't think that's the way to decode this....

And how do you come up with last week of March/beginning of April when it's the 10th week ?

January 1st was a Saturday in 1972:

So let's say week 1 ended on Saturday january 8th

2nd week = 15th

3rd week = 22st

4rd week = 29th

5th week = 5th of February

6th week = 12th

7th week = 19th

8th week = 27th

9th week = 5th of March (leap year)

10th week = ending on March 12th

 

My rear seatbelts are retractable which are cool, is this rare to have these in a 72 convertible?

 

Erik,
First of all that is the way seat belts are date coded.

As far as the build date for the car, I checked my information for similar date coded 71-72 cars and found out the seat belts were running about a month behind the body build date of the cars, therefore a production date for the car right around the last week of March to the beginning of April of 1972 would be just about correct. Some may be dated closer, some later, but it gives you something to go with.

Now you guys can believe me or not, it doesn't matter to me.

Duane,

Nobody said that he/she didn't believe you (at least I didn't).

First I said I wasn't 100% sure about the way I decoded it myself (before your post), and second that I have doubts about your way of reading the code. But I never claimed you were dead wrong, or that I was right with the first explanation.

So a 1973 Riviera has an E on the seat belt code, because it's an E-body car ?
But are the seatbelts on a 1973 Riviera different from the ones used on a B-body car like a 2 drs LeSabre HT of that same year ?

 

Not to get in a p*ssing contest here but here is what I was told some yrs ago by an AACA judge and it made and makes sense to me.

The first number/s are for the week they were produced, the letter represents the plant where they were produced--I have no idea on where to get/find these codes and the last number represented the yr produced.

I have just sold a set of seatbelts with a K on them removed from a 71 Cutlass which I just parted out and I have seen B and C in concourse Firebirds/Trans Ams and I know they are F bodies.

HTH, once again it was what I was told and what I observe, especialling knowing that some of these cars were original such as the 71 Olds and they have not been changed out.

 

In fact I just did some searching and here is what I found for the plant codes. This is taken from a chevelle sight, in fact one guy even has K coded belts in his chevelle.

K=standard Robbins (Chevelles and others, DAAL labels were put on Pontiacs, maybe others)
A=Standard Irvins (Camaros & Firebirds only)
A=Deluxe General Safety (not sure usage, large cars)
B= Deluxe Bay Trim (not sure here either)
C,D,E,F=deluxe Hammills (Camaros & Firebirds only)


Now remember the references are toward Chevies so that is why you are seeing referalls to the chevelles,camaros and firebirds, afterall it is from a chevy site BUT GM used the same manufacturer across their lines.

I took the above info from the following link
http://www.chevelles.com/forums/showthread.php?t=76238&page=2&pp=15&highlight=seat+belt+code


so you have the Irvin plant, Hammill plant, General Safety, etc etc
once again, not starting a contest on who is right or wrong, just what I was told through the yrs and my observations!! I do know that the Hammills are used on the Buick and Olds for their deluxe belts.

HTH

 

Everything I have ever seen had the A codes, so I assumed they were for A-bodies. It's nice to know that information, thanks Bill.

I knew the other info about week/year was correct.

Duane, you're welcome. My 72 GS in fact has the A code on its belts (8A72) and I have to agree that most of the A body Skylarks, GS's I have seen were A codes, very few were other, yet most of the Cutlass's that I parted out were K's or B's. Heck maybe it has something to do where the plant was located?? Who knows.

Take it easy.
