67 seat belt codes

[Richard B.]

i have been reviewing the archives on subject of 1967 seat belt codes. It seems that the 1967`s have:
HAMILL 1967
MODEL C10
and then a date code

Mine read HAMILL 1966
MODEL C10
no date code is visible

The car is from late October 1966. Is HAMILL 1966 consistent as original for the car or should it be 1967? Do the date codes disappear or were there some early cars without date codes? Are these belts form a 1966 car? The markings on the belt buckles are consistent with original equipment for 1967 cars.

Re: 67 seat belt codes

it sounds like someone replaced your one belt form a newer 67

Re: 67 seat belt codes

Yes, it is common to see the dates disappear with use over time.

Rich. All 1967 labels should say Hamill 1967 C10. The hand stamped ink date at the bottom of the label will reflect the week of production. In your case it would probably be around * 40E66 *. The stamped date often fades with age and sometimes goes away completely. Your belts were probably changed sometime in the cars life. Late 66 and 67 buckle bases have indentical markings.

Richard,
Both original seat belts in my 67 with an assembly date of Dec.7, 1966 has the following markings:
HAMILL 1967
MODEL#C10
47E1966
It is said that the "47" is the 47th week of the year the belt was produced, which in this case is November, and supposedly the "E" is for Friday and 1966 is the year in which it was produced. Supposedly only the letters "A" through "E" were used in the date stamp.

Re: 67 seat belt codes

Thank you all for the responses. It appears my October 28, 1966 car has 1966 seat belts that are otherwise correct for 1967...with a worn off date code. I suppose it is possible some leftover 1966 stock was used up on an early car but imagine it is more likely the originals were taken out when the car was at the race track (or something like that) and some correct color belts were restored from 1966 stock. I have had the car judged twice and have been deducted for "no date codes" but so far no judge has picked up that these are actually 1966 belts based on the "HAMILL 1966".

Re: 67 seat belt codes

Warren, you're dead-on with your dating description.
FWIW.
Due to the Corvette requirements being so relatively small in the overall GM scheme, the Corvette belts appear to have been batched for production on Fridays, since we typically see the "E" in the day section of the code.

................supposedly the "E" is for Friday ........

The idea that Corvette seatbelts were only produced on Friday is an Urban Legend. There are tons of Passenger car belts also with an E code. I have also observed A, B, C, F and H codes used in passenger cars and trucks.
In the Early 80's I spoke with someone that was a plant manger at HAMILL Mfg. He explained that the letter represented the section of the plant that produced a certain style of belt ( retractable, non retractable, car, truck, etc.). This notation was added to the 1970 judging manual. It needs to be added to other manuals that reference HAMILL seatbelts. I hope this sheds some new light on this topic. Clete

Our CRG (Camaro Research Group, www.camaros.org) research on '67-'69 Camaros has led us to exactly the same conclusion - the letter denotes the line or department within the plant where the belt was produced.

Clete,
What about the Air-Chutes?

Re: 67 seat belt codes

One thing I noticed in my car was the fact that the passenger seat belt code could just be made out even though the driver's side was completely worn off. Probably a result of less use of the passenger belt.

Also, were the optioned shoulder belts (which my car has) date stamped as well? Thanks.

Re: 67 seat belt codes

Richard, for what it is worth, my early 67 (VIN 100183) has 1967 dated seat belts. Although, I've been told that I have 1966 windshield wipers.

Re: 67 seat belt codes

Mike. Yes Air Chute belts had a date stamp. I made reference to this on July 29 in this post. https://www.forums.ncrs.org/showthre...62480&uid=3716 . Please see the photo

Re: 67 seat belt codes

Kirk, Yes shoulder belts were also date stamped. The date stamp is usually sooner than the lap belts because fewer cars were built with shoulder belts. Clete

Re: 67 seat belt codes

Hi Clete
Yes, I remember the pic. Somewhat similar configuration on both.
My question was what is/are the alpha codes on the Irvin Air-Chute labels and what do they represent?
Weren't the lap and harness within a set the same?
