 I'm beginning to think they changed belts mid year in 71 along with a number of other things. 

Hi Mark , I do this before someone does. The change was made around in February ( export) or March (Japan) 1971 , there is a service bulletin which is titled’ 1971 late models ‘ introduced a set of new seat belts as well as other numerous changes.

It is Interesting to see two books were written in different way , different depth of technical descriptions.

No no... zedhead.. this is a feb (2) 1970's car were some moron thought i put a one (1) in front of it, while the plate is ON the car..  (would be spectacular when someone finds out the laquer under the plate is damaged only were the 1 has been hamered into it!)  

 

BTW... I'm just kidding... or AM I??    I ask myself: Are there more people with such a strange fat 1 in front of a "normal thin "1" or "2" ?

This placard is useful for US and Canada model to determine 70 or 71. And Manual or Automatic transmission.

Now I would like to know when Nissan Shatai put this placard on to their 240Z . September? October? November? 
If we can get enough examples, we will be able to see when . 
By the way, Japanese people usually say about our cars first- registration month and year . Only enthusiastic people say about build date with chassis number .

Of course one could simply buy one of my reproduction under hood decals and/or one of my door jamb ID plates and cause much havoc in the Z car world while providing much entertainment for dutchzcarguy. Perhaps someone already has done so!!

My car is a 7/70. #6521 and has a slightly different emissions decal. It also references the 1971 regulations.  The interesting thing is that my car is a non-emissions model for the Canadian market and came without the emissions devices mentioned on the decal. Here is a picture from before I removed if during my current resto.

 

Here's a link to a discussion on this subject. Might be a good place to continue this discussion.

 

It's an old topic that's been examined, apparently, of course.  But the BAT guy got more views probably by claiming 1970.  Still has questions to answer in the comments.

Here's Carl Beck from 2006.

Most manufacturers call out the changes in the new model year when they introduce it in their sales literature.  They almost never say "it's so good we haven't changed a thing!".  Does anyone have a 1971 240Z sales brochure?

Interesting bit on the value of 1970 vs series one 71's...

 

"Is a 1970 240Z more collectable than a 1971 240Z?

As not too many people are fully aware that there are two "Series" involved in the 1971 Model Year cars, for the most part, the answer to that question is YES at the present time. As the Model Year limits the quantity available, the 1970 240Z's will retain more of their value, and will be easier to re-sell over the short term. (three to five years)

However, if the Z Cars follow the patterns established by other imported collectibles, then the Series I cars will, as a group, be recognized as the Original Z design... and for the most part the Model Year under which it was titled, will not matter as much as it does today."

 Somebody sloppily pounded a "1" on my 2/70 z too! 

I like to refer to mine as a "1969 3/2" model year.  😉

You have a good hand for VIN poker. Three of a kind, lucky seven.

When you take a close look at your plate.. i think the 2 is the fake later placed number as there is a much bigger dent around the "2 " ? Like the dent around the 1 in the earlyer picture? 

When the Japanese worker hit it with the " 1 " on the bench i guess the indentation is deep and you have no dent around the digit..  When you "illegal" put in an extra number while the plate is on the car you make a much bigger dent and the digit itself has less deeper indentation..

You have to enlarge the picture to see it properly.

I wonder if you can see something of a indentation in the paint behind the 1 or in your case the 2?  Drill them rivet's out and get yourself 4 new ones!

On the other hand those 2 cars could be from dec. 1970,  the chassisnumbers are not that far from each other.  Maybe Mr beck @Carl Beck  knows If the chassisnumbers fit the dates..  (And that Japanese mechanic used some different height of letters/digits to identify these cars..)   

(My translator does not give a name for "slagletters/cijfers"  so i like to know what you call these tools to hit with the hammer to make the letter/number on those plates!  Thanks!)

From the VIN’s I have collected, I have 12/70 starting at HLS30- 15361 and running though #18048.  01/71 starting at 18144 and ending at 20533,

 

It would appear that the Metal Data Tags (Door, Engine and Dash) were produced first on an Addressograph type machine - where serial numbers were stamped sequentially, like the 17770, followed by 17771, 17772 etc..

Then the date the car was finished at the top was hand stamped with a metal number Punch Die (aka Metal Numbered Die)
