This buyers guide / identification guide has been written for those interested in the 1968 - 1970 Datsun 2000 roadster (known as the Fairlady roadster in markets outside of the U.S). Please note, due to significant changes between the 67/68 model years, we have a separate ID guide for the 1967 Roadster (click here).
This guide bundles the 1968 - 1970 SR311 and SRL311 cars into one ID guide, as these cars are all quite similar other than minor aesthetic modifications between the years which are outlined in detail below. The 1968 - 1970 Datsun 2000 roadsters are a very desirable version of the Datsun roadster, becoming increasingly sought after by collectors and enthusiasts. These cars are based on the same chassis and body of the 1600cc Datsun roadster of the same era, and as a result, occasionally cars are re-birthed or misrepresented to unsuspecting purchasers.
The purpose of this guide is to assist people in the accurate identification of genuine 2 liter roadsters from 1968 - 1970, and includes information on external and internal features, original paint codes, chassis and engine number prefixes and a basic summary of the mechanical features of the car.
Period of Manufacture: October 1967 – April 1970
Production Numbers: Approximately 15,000 Datsun 2000cc roadsters were produced in total over the period 1967 - 1970 (including 1967 ½ cars).
Please note, this guide has been written based on a variety of online sources and enthusiast input. You should not rely on this guide to make any purchasing decision and we make no representation that all information is accurate. You should always seek independent professional advice when looking to purchase a unique car.

The following external features should be present on the 1968 - 1970 Datsun Sports / Fairlady 2000, making a good starting point for identification of a genuine car:
Features consistent across all model years:
Features unique to RHD market cars:
The 1968 - 1970 Datsun 2000 Sports / Fairlady had the following interior features:
The following paint colours were available on the Datsun 2000 Roadster. Examples of each colour are provided in the attached images.
Confirming the cars original colour:
The paint colour and code was printed on a label under the bonnet to the left of the ID plate (See images for a better description). Of course, labels can easily go missing by peeling off over time, or are removed during restoration. If the label is missing, your best bet is checking under the carpet on the transmission tunnel or on the inside of the firewall for signs of an original colour, and trying to then match it - assuming you are wanting to restore the car to its original colour specification.
The 1968 - 1970 Datsun Fairlady 2000 Sports should have a chassis number in the following format:
Left hand drive cars = “SRL311” – followed by a 5 digit number.
Right hand drive cars = “SR311” – followed by a 5 digit number.
1968 cars: The 5 digit number within the range of 01001 through to 06999
1969 cars: The 5 digit number within the range of 07000 through to 12999
1970 cars: The 5 digit number within the range of 13000 through to 14500
Location of Chassis Number:
There are several locations you can check for the 68 - 70 Datsun Roadster:
1. Check the chassis plate / VIN plate which is located under the bonnet, riveted on top of the flat area just above the RHS bulkhead/firewall (see location in images). The chassis number should be in the location per the examples shown.
2. Check the front left top side of the chassis frame itself. There is a stamped chassis number just below the area where the washer bottle is fitted in the engine bay. The stamping may be difficult to see so you will need a torch and may need to clean off paint / grease to see it clearly. See the images attached for the location and stamping font typeface.
3. On 1969 - 1970 cars, there is an additional chassis number located on a small plate at the top of the drivers side dashboard, visible through the windscreen (see images for better location description). Note, this can be lost / changed if the dash has been changed.
The Datsun Sports / Fairlady Roadster 2000 should have a U20 engine prefix, followed by an engine number that is around 300 - 600 numbers higher than the VIN number. The Engine number should be in two places.
1. On the VIN tag / chassis plate on top of the bulkhead, stamped above the VIN number on the ID tag (see images)
2. Stamped into the RHS top of the engine block (See small flat area sticking out), where the head and block join/meet (see images).
Some have reported that there are cars with tags that have no engine number stamped into them. For those cars, check that engine number is within the 300 – 600 higher range as noted above, so you can at least confirm the likelihood that the engine is original, or confirm that it is from approximately the correct year/era.
