On a 1970-73 this is the breakdown
H: 2.4 engine
L: left hand drive
S30; the base number model of all early Z's from 1970-76 worldwide.
09977: the actual serialized number of your left hand drive 240Z.
In the UK/Japan the VIN HS30... 2.4 liter. RHD
RLS30 or RS30; R= 2.6 liter.
S30; 2.0 liter RHD (Japan only)
For 1974 US vehicles,ie. 260Z, a unique VIN of RLS30...... Then in 1975 Nissan introduced HLS30 for North American vehicles. The H representing the 2.8 liter engine, 2.6 was used in the rest of the world as the performance engine until 1979.
After the introduction of the 17 digit VIN other information is listed such as country of origin, restraint system, trim codes,emission codes,etc.(North America only).
You have a late 1970 240-Z.
My VIN # is HLS3043247. The car was manufactured 9/71. By title it is a 1971, however, by parts is where it gets interesting.
Since I don't have access to Nissan's logs, I'm taking this information from Victoria British's chassis number identification. They list that serial number 046000 should have been the last number produced in 8/71 in order to qualify being a 1971, and that production for the 72s started in 9/71. Right there I have a discrepancy between what's on the car and what is published.
Checking Z-Home (www.zhome.com), shows that my VIN# was in effect produced during the time period on my car. They list VIN# 51583 as the LAST car reported so far as being a 1971, and the earliest 1972 as 48863. Obviously there is some overlap, and this is partly due to the various dealers that sold the Z accross the USA. Sometimes they would license as a 72 to take advantage of higher posted MSRP, or taxes etc.
The key thing behind this rambling, is to check with various sources as to what YEAR your car is. In my case, many parts are indeed 1971, but I do have bunches of others that match 1972. The basic message to all is to check your # against PRODUCTION logs and don't just subscribe to the thought that TITLE year equals year of car. This is especially true if going for a top notch restoration or concours.
By the way Edward, your # shows that you are well within the 1970 Series One Body Style numbers. With that info you can discern whether an item will work for your car or not.
