I recently received the Marti books and was hoping I could find date related sequential unit numbers. They are the last 6 of the VINS for each year.

I'd like to know the VIN for the first and last Mustang produced for each year.

I also realize that the VIN will not always be the deciding factor as to date assembled. Because some cars could be scheduled and bucked, receiving a VIN and then held up due to parts availability; especially for special ordered cars.

And for that reason maybe I could get the first/last date of production for each year - even that would be useful. But I cannot afford to pay Marti's folks an hourly rate to look this information up... My blank check would BOUNCE real quick! LOL

I had considered using the REGISTRY here on this site but I don't think it would provide enough info.

Anyway, I was just wondering if anyone had any insight on this?

Thanks!

Ray,

You could do a post like I'm doing for the year and model and let folks add the last 6 of their VIN or Maybe Rocketfoot could add something to our Data page.

 
Ray can you tell anything about the last 6 of this VIN? From 71 209271

 
To keep the conversation going, my initial thought was that since the first VIN for each year is supposed to be 100001, the following should apply:

In 1971, there were 149,682 Mustangs built, so the last VIN should be 249682.

In 1972, there were 125,093 Mustangs built, so the last VIN should be 225093.

In 1973, there were 134,867 Mustangs built, so the last VIN should be 234867.

...but I KNOW this is not correct because my 1973 Grande has a VIN of 244824.

So, I may be mistaken in thinking that the Mustang line begin with VIN 100001. Then again, there may be other factors at work. Perhaps some of you may be able to provide additional insight.

Great Posting, Ray!

Not sure if it helps but the last four of my vin is 1659 on my 71. Marti says it was build on 12/70 and sold on 1/12/71. Not sure when in 70 they started manufacturing the 71's.

I always thought the consecutive number included all Ford vehicles in that particular year. so the serial number of a mustang could be followed by a pinto or maverick or LTD.

Correct, almost. The consecutive number didn't include all Ford vehicles...only the following vehicles were all numbered together:

1971:

Ford, Tornio, Maverick, Mustang, T-Bird

1972-73:

Ford, Tornio, Maverick, Mustang, T-Bird & Pinto

 
Consecutive numbers were from the same assembly line, regardless of the vehicle models made on that assembly line.

 
Ray,

I have an interest in the same type of information. I have done some data gathering for the 1973 model year since I have two of them. I have used the Marti report forum on this site as well as advertisements for cars for sale that had Marti reports to obtain a general idea of which serial numbers were produced in which month. Here are some examples (last six digits only):

Earliest 1973 Mustang I found data on: 121758 produced on 9/14/72

The highest serial number I have seen: 263742 produced on 7/3/73

The latest produced Mustang I have found is: 260846 (7/5/73)

Here is where things get interesting. My car's last six :260846. This is 2900 vehicles by serial number earlier than the largest serial number I found but my car was produced on 7/5/73 (it was behind schedule). My other Mach 1 is 261106 - a larger number but produced earlier on 6/29/73 (ahead of schedule).

What I have seen is that a 1973 Mustang that has a serial number of approximately 170000 or earlier was produced prior to 1/1/73. Those cars with 250000 to 260000 were likely produced in June 1973 and above 260000 were produced in July 1973 (there are a lot of exceptions to that though).

I would be interested in knowing when the last day of Mustang production was in 1973. I have seen no data on Mustangs produced in the second week of July 1973 so I am thinking that production must have ended in the first week of July 1973.

Steve - wow. Great job!

I see this type of information is popular.

And your info confirms something I considered - the date is a better basis point to use. VINS are all over the place.

I'll have to think on this more but will probably start a new thread polling for the last 6 and the buck date??? or ???

Need to tie it together somehow...

Ray

 
Ray,

I think a poll of the last 6 and the actual build date would be interesting. One of my cars was bucked 3 weeks after it was serialized but it was rolling off the line only 2 days after being bucked. Thanks for starting this thread - very interesting!

 
Ray can you tell anything about the last 6 of this VIN? From 71 209271
It would have most likely been produced late May 1971. What is special about the car?
I'll keep you posted if it joins the family!

Ah, I see. Could be a very special one then. ;)

I have a keen interest in April/May 71 build cars and also the Bond Diamonds cars. I have 180695 March 9, 71 (5 days behind), 197441 April 28, 71 build. I also have a very early Oct 9, 70 build Diamonds twin car, 124540 (7 days ahead).

I almost bought car 204071 that was built on May 13, 71 (on schedule).

The first cars were serialized in late July 1970. Production started on one of 3 days: Aug 1, 2 or 3rd, 1970. I don't know for sure but highly suspect it was Aug 1st.

The first Mach 1 was 1F05J100031 built on Aug 3. 1970.

My understanding also is serializing of vehicles produced by location started at 100000 but that was for all vehicles at that plant ie F for dearborn. My 71 was serialized 7/70
Jenny, I noted back when you first joined that your car was a very, very early 71M-code. A very cool car in my book! It was built on Aug 11, 71 as a test vehicle for Ford.

Steve, does your car 260846 have traction-loc? I've noticed on the 71 & 72s that t-loc equipped cars were usually built behind schedule. My guess is that Ford didn't have enough t-locs in stock and these cars were delayed.

I have 2 73s built back to back. 226499 built on 5/3/73 and 229193 on 5/4/73.

I was wondering about this too; my 73' Grande is 263747 but I have not gotten the Marti on it yet.

BTW

May 27 build date on schedule
