Thanks for the numbers Neil. This is the kind of stuff i love.

The magic number for Australian KB10's [Datsun 1000 coupes] is KB10-080 001
From this number upwards, they are regarded as 1970 models, first released in July of 1969. It would seem that production was discontinued in December of 1969.

Anything below this number is regarded as a 1969 model.
The '69 model year for Datsun 1000's generally started from September of 1968, however, i believe that Sidedraught has a '68 model sales brochure for the JDM Sunny range that aslo includes images of a coupe. If i can get a look at this document, or find something that he wants to trade for it, i will get a better idea of when the KB10 was first released, but i suspect that the Sunny Coupe was released right at the end of the '68 model run & may still have been regarded as a '69 model car.
[Hint hint Sidedraught,...trade, hmmmm]

The two serial numbers are only 166 units apart, so it's even possible that they were shipped on the same boat. Well,.... you never know.

For the record, the chassis number for my coupe is KB10 - 090 686 which clearly makes it a '70 model, & probably near to the end of production.

Any other KB10 owners are invited to let me know their chassis numbers, either via this thread, or by e-mail as i would like to build a databas of chassis numbers to help in future research. Thanking you in advance.

You could try ringing Nissan in Australia & asking them. That's how i came to find that my series 2 Bluebird wagon was built in late Feb of '85, almost three weeks after the official launch of the series 3 Bluebird model. The plate was even stamped 02/85 which confused my local parts bloke.

Just to drag up an old thread
I finally got my orange coupe home and into my shed
I thought I'd post the body #'s up for Dodgeman to have a look

Orange coupe - 052143
White coupe - 052309

On a side note, is there anyway to trace through nissan/datsun which engine numbers came with which chassis numbers, and vice versa?

Chassis numbers are often allocated by the factory in blocks for each callendar, or perhaps model year of production.
If your coupes started at LB110 -70,000, then it's possible that a block of, well, say 15 or 20,000 numbers were allocated for the first year of production. The following year could easily have another block of numbers that seems to be unrelated to the first block.

By way of example, my right drive Datsun 1200 book lists the 1200 two door sedan as follows.
Model B110 [A or T] RU. The A or T is for auto or manual trans.
From C/# B110-247023 from April '71 [Z]
From C/# B110-341001 from Jan '72 [Z]
From C/# B110-655001 from Jan '72 [N]

What does the suffix meam? Beats me, but the point is that the serial numbers were allocated in blocks that were large enough to cover the anticipated production for that particular [sub] model.

The right drive 1200 coupes are listed as
Model KB110 U
From C/# B110-877228 from April '71 [F]
From C/# B110-940001 from Jan '72 [F]

When a follow-on serial number range starts with a number that ends in 001, you know it is part of a block.
Strangely, this range of numbers does not start with KB110. Most odd

I'm sorry that i can't help you out with the left drive serial number range.

what am I missing here if the coupes started from LB110-70001 and there were 89,541 (coupe) by doing the math then the last coupe should be numbered LB110-159542, then how is my coupe LB110-5XXXXX?

Excelent, I got the vin/chassis number part covered. How about the engine number?

It doesn't matter how many numbers there are, they are the Vehicle Identification Numbers whether they are on the dash or firewall.

Look at the title for this vehicle you are buying and you will see that the numbers listed under Vehicle Identification Number will or should match the numbers on your car.

Strictly speaking, these are chassis nunbers. The use of 17 character International VI Numbers [VIN's] did not happen untill some years after this.

If your car is a LHD coupe the prefix will be 'KLB110'. K being coupe, L being LHD.
The VIN could be different things depending on where you are.

Why don't people put their location in their profiles???

Thanks man, unfortunately the car doesnt have a dash board in the car (by dash I ment the dash in the number on the firewall), from the numbers and letters you gave I can now figure the chassis number on the firewall, which from what you said is the same as the VIN.

How about the engine number any info on that I can see A12, but can't tell the rest untill i go there with some carb cleaner and a hammer to get the gunk off, how many numbers are there after the A12?

Thanks again
