4732920724

1973
29th Week
2 = Tuesday
0724 = Consecutive Chassis number

Is that right?

no can only get it from the karmann number, this guy does not have his karmann number hence need to compare his id number to others in the world data base to get a range for the month produced

- Go here http://www.914world.com/bbs2/index.php?act...amp;byYear=1973

- Look for any VINs close to 4732920724

- Find VINs with either a "c" (Chassis Number) or "d" (Date Code)

Closest previous VIN with a date code:
4732920632 04/73

Closest following VIN with a date code:
4732920782 - 05/73 - 1839593


@dr914@autoatlanta.com
Since 4732920782 was the 93rd car made that day and 4732920724 is only 58 cars prior, it stands to reason both cars were made on the same day.

@Root_Werks

No, you can't use the VIN, you need the chassis number, which the Dr. doesn't have.

Now that I have thrown away the ferric oxide foil trunk floor, where would the chassis number have been?

If anyone has any issues with it let me know and I can modify it. Appears to work correctly for my 1974 (IMG:style_emoticons/default/smile.gif)

Thanks Sir Andy. Yep, that is gone. Now I also have to deal with replacing the driver’s B-pillar label. Any suggestions? I have of course saved that piece.

I thought the 29 is the Karmann Factory designation.

My Vin is 4732921258 and was manufactured May 19, 1973 per COA.

Not sure how many cars were produced per day.

Punched Early VIN Label

Punched Late VIN label

Apparently Car-Bone is a possibility, per this thread. No recent updates: Door Jamb VIN Sticker Thread

I bought a Door jam sticker from CarBone and love it. Mine was toast anyway. My mistake was getting a black one instead of silver like it should be . Oh well, looks cool.

@914Wes
Line 11 is incorrect.

The 95 will roll over to a 96 if there were more than 99 cars made that day.

So your daily_sequence should be computed as:
CODE

roll_over = int(chassis_number[3:5])
daily_sequence = int(chassis_number[5:7]) + ((roll_over - 95) * 100)
