VIN, VIN...Why do I need to know my VIN?
What is "VIN?" VIN is the Vehicle Identification Number, also called car number, chassis number, or serial number.

In actuality; most roadsters do not have a true vin. Those were required on foreign vehicles beginning with 1969 production; some sources say January 1st, 1969 production. At that point a dash mounted vin plate was required. Nissan just used what they have always used to identify their cars; the "car number" also called the "serial number" or "chassis number" or "build sequence number" which is the model designation followed by (in the case of the roadsters) 5 digits. In the case of the 1500s; most had a number and a hypen in front of the model designation and a letter after the 5 digits. I have heard and read of a number of explanations of what these signified (year built, model year built, shipped year etc) None of it jives when you look at a huge number of them.

Anyway; in 1969 the cars all got a "real" vin tag on the dash but it is supposed to be on the cowl of the car; on a non removable non tameable tab. You can just yank the dash out and "revin" your car! Of course their is the hand scrawled number on the frame...

For simplicity sake we refer to the SPL310-02222; SPL311-03333 and SRL311-04444 as the "VIN" even though technically they are not a true vin but the car#, chassis# etc. DMV looks at that number as a vin.

Datsun Roadsters are titled by the year they were sold, not necessarily the model year they really are. A true 68 could be registered as a 69, a true 70 could be registered as a 69 etc. Before 68 the cars came with "vin" tags that had 1 9 6 _ and the last digit of the year was later stamped in, or just replaced with a later tag. SPL310s sometimes had a 3-4-5 before the SPL310 or before the 5-digit vin suggesting (we think) what model year the car truly was, regardless of what was stamped above for the licensing year. Just to make sure nothing makes sense we've also seen some examples that would indicate it signifies CALENDAR year produced, not model year. They also could have a letter after the vin. Only theories at this point to the significance of the letter. Also, in some cases we believe the cars were built and put in storage lots, but the most recently built cars were pulled for shipment first. That could help to explain why the very first Fairlady sold in the USA was (a 1960) SPL212 00198 (out of 288 built). All of the 61 and 62 212's I've found have had lower numbers. The same thing may explain why some of the lowest vin numbered 1500's were titled as 64's and had very high engine numbers. (end of the 64 run of engines) Just before they switched to the 65 models they must have found these engineless chassis or bodies gathering dust somewhere. Or was an defect found in the engines causing the cars to be set aside until later? Or did someone squirrel away the pre vin-stamped frames until the very end of production when they were again "found"?

Historical details of what Nissan did in the 60's are often debated. An addition to the weirdness file was recently sent to us (thanks Tim). This roadster's vin number on the frame originally began with "00". It was then "X-ed" out and two "1"s were stamped below it. (pic). Above the original number were two Nissan logo stamps. What was this, the guy forgot to change the numbers in his stamping tool? Or a 1965 frame was lost and then "found" later? The 67 1/2s used a different frame though... That could of course been rectified as I've seen other modifications done to make the parts work with what they needed at the moment, especially to fenders. Cars with fairly low production figures are always interesting.

The thing to remember is that the year the car was sold has nothing to do with ordering parts for it. Learn what's what. (It'll help you) Any roadster enthusiast worth his or her salt would never refer to their 69 as a 70. Please see "Year Your Car Really Is."













OMELET CARS...little bit of this, little bit of that...
We have seen a number of cars that various owners have re-assembled from the pieces of other cars. Not necessarily a problem unless different years are mixed together. Unfortunately your frame number may match your title and tag under the hood, but may not match the body of the car. True 1969 and 1970 models had a riveted
vin tag on the left side of the dash, visible through the windshield. Unfortunately it is not riveted to the cowl, it's riveted to the dash, so if the dash is switched, the vin tag is moved also. On January 1, 1969 Nissan began installing a vin and production date tag on the driver's door post, but it was glued "tamper resistant" rivets until shortly after 1970 model production was begun. Unless you know the history of your car, we suggest browsing our "Year Your Car Really Is?" page to learn how to spot the differences, and to help you verify your own car's attributes as correct. Although we can 99.99% guarantee you'll get the correct part your car originally had if we have the VIN, if your car's been modified it's anyone's guess. That's OK, we enjoy descrambling mysteries and will be happy to keep working with you until we both know what's on your car.

Our responsibility ends with providing the correct parts that match what originally came on the car you gave us the VIN for. So if in doubt give us shout.
