67.5 2000 Roadster Guide

67.5 2000 Roadster Guide.

This thread will create the 67.5 2000 Roadster Guide for the 311s WIKI.
The object is to gather all the features and unique data that identifies the 67.5 2000 roadster.
There are some 311s members who know this info and it needs to be gathered into one
document so that all members can have access to it.
To be as complete and accurate as possible this guide must be created by 311s members
and will require input from all those with knowledge of the 67.5 2000 roadsters.
Below is an incomplete outline of the subjects that should be included.
Feel free to add other areas that I have not listed.
I have started the guide with a discussion of "matching numbers"
Pick any topic you are knowledgeable about and and create a definition, description, discussion, review or analysis
and submit it as a post to this thread or send it to me directly at tcheaton@hotmail.com if you do not want to participate
publicly. There will be no author attribution for any of the contributions that go into the WIKI guide.
Include pictures (and send them to me) to illustrate your information if possible.
I will add the contributed information to the guide which I will maintain in the cloud and
post a link to the guide so all members can follow the the current version.
I will post all added/edited data here for member review.
This may take many iterations and hopefully it will keep building into a useful guide for
those buying and selling a 67.5 2000 roadster.
There were only 67 2000's but we will use the commonly accepted term 67.5 2000.
The info should be specific to the 67.5 2000 and as Joe Friday used to say on the early TV show Dragnet,
"Just the facts Ma'am".

Matching numbers.
Matching Numbers means the roadster frame and the engine are the same as when the roadster was built.
The car number is stamped on the left frame rail just below the front carburetor.
The engine number is stamped on the U20 block just below the coolant thermostat housing.
These numbers should match those stamped on the ID plate on the right side of the cowl.
Having matching numbers is considered important for confirming that the roadster
is stock in that the original engine block is related to the original frame.
Even if the numbers do match how do we know these are the original frame and engine block?
Over 50 years changes may have happened. The frame may have been bent and replaced.
The frame section where the car number is stamped may have been replaced by a section from another frame.
The motor block may have been changed. Replacement blocks available from Nissan
have no number stamped on them. The original engine # may have been stamped on the replacement block.
The cowl ID plate may have been changed to show the changed frame or engine block.
Proof of matching numbers can be difficult to confirm.
Is the cowl ID plate the original one? Most seem to be lost. New blank ID plates are available.
The stamping font on the original tags is unique and a number punch set from Harbor Freight
will not be the same. An original tag should show some indication of age and is attached
with 4 metal screws not rivets.
Lacking firm records such as an original sales document with the engine number (rare)
or a chain of service records with the engine number (again, rare) a decision must be made
on a "seems reasonable" basis.
For the 67.5 2000 this a satisfactory method because there is a relationship between
the car number and the engine number as is shown clearly in the 311s registry.
Though the U20 was a new engine for the 67.5 2000 the car and engine numbers are not
shared 1 to 1. The U20 engine number is anywhere from 100 to 700 higher than the car number.
The registry shows Car #3 with engine #104, Car #79 with engine #227, Car #155 with engine #454.
So some number relationships (fictitious examples below) can be seen as not right.
Car #15 with engine #4005. Not good.
Car #700 with engine #215. Not good.
Using roadster #585 as example we can try the "seems reasonable" test to verify the claim of matching numbers.
#585 has a replacement cowl ID plate. There is no original ID plate. The restorer claims it is a
matching number roadster. Not much real proof here.
The engine number is #1003. The registry shows SRL #573 with engine #885
and SRL #588 with engine #1000.
Again not positive proof but "seems reasonable " that engine # 1003 was original to car # 585
as it fits within the roadsters on either side of it in the registry.
This may be the best we can do for most claims of matching numbers.

I had a webshots album filled with '67 SRL-specific pics...I'd love to contribute from my archives but I don't have any verified documentation to support the pictures, ie they're all recent restorations. How serious is this document?

[ted heaton]

Hey Alvin,
Thanks, We will need the pictures to show members what the parts being described look like.
They will be validated/verified by consensus of the guide contributors. If the picture is of a non stock part all the better
to show the difference.
Maybe do it this way. After a contribution about a specific part send pictures of that part.

Ted.

Ted, just for further reference, below is a thread I started a couple years ago discussing 67.5 engine numbers. Although may be somewhat irrelevant since Steve added engine numbers to the registry. FWIW

Just wanted to say thanks to all who are working on this . It will be a great help to all of us who are restoring our cars and want to make sure they come out correctly

[jamesw]

I have owned three 67 2000's and I purchased one of them from the original owner - so i'm happy to help where I can contribute.

Cheers
James

Satin headlight buckets?

[Curtis]

I can tell you at least for the hood harness the original is not the same as the later replacement harness from Nissan (1980's one still brand new). So if you want the engine electrical to look like 1967 then you have to use the old style or have it built that way.

Add to that I have been told that sometimes the temperature sender wire was just extended across the front of the engine from the 1600 exit point on the harness. I haven't seen one in person as yet. The examples I have have the wire exiting with alternator wire.

[jamesw]

Front fenders are unique to 67.5 as they have wide flare but are designed to join at the doors and low windshield with a different shape than later fenders.

[ted heaton]

Thanks to all who have posted.
I added the mentioned headlight scoops and front fenders to the Guide outline.
Also added a line for 150 HP parts.

cole455. Thanks for the link concerning car and engine numbers. Good reading. I missed that in 2013.

Curtis. Thanks for the harness info. Is there a unique 67.5 2000 harness?. If so how can we identify it?

jamesw. Thanks for the fender info. What we need is a picture of a correct fender where it meets the door top on a 67.5 2000.

For everyone,
pick any of the points in the outline to expand on. It can be as short as a sentence as James did with the fender.
It just needs to be identified so we know a difference does exist.
As with the fender there are many 67.5 2000 parts that are shared with the 67.5 1600s. This is good for parts availability as
they can be found on the 1600 roadsters.

Nice Alvin-great start with some very good pictures. Excellent idea Ted. Hopefully we can do this for all the models at some point.

Great pictures as always Alvin. If we are creating a guide of what a model should look like, wouldn't the judges from the big Datsun shows have something that list specific items. I'm an east coasters, but I assume the Shasta and Solvang show use community members as judges(?)...it would seem like there is some list out there that says model x has... I do appreciate this thread as I finally see a 67.5 2000 radiator shroud.

It's been my experience that all the US market 67.5 2000s I have seen have 135 HP VIN plates regardless of carb type. When they do have Mikuni Solex carbs fitted they are the early type (2 screw jet cover).

[S Allen]

So my car is already worth less. I have the later(better) style Mikuni Solex carbs. Oh well, I will still enjoy driving it when I get it done.
