matching numbers car

Soaring you dont know what your talking about,,,,didnt you read !!! Sheeesh. Vin is but one of the things considered in numbers matching and vin stamping on the block, like a lot of early cars just wasnt there. Numbers matching is about more then that. Do some research Soaring like you like to tell others!!
Fritz you will find those dates on most sheet metal that is stock. For instance look at your front fenders on the strip under the hood and you will see the same sort of date code if it is a stock fender. That date codes identifies month date and shift it was built. Even the original clamps were date code stamped. You will find these date codes on a lot of pieces in your mustang and they should match the build date shown on your door tag and be correct for the consecutive unit number on your Vin. You havent given enough information Fritz because 63A is the body style- fastback standard, and M is the color - Wimbledon White. The next two numbers are trim and then the date code (on your door tag).  

48: The date reads 11L followed by DSO 23. Do you or anyone know what this means?  

Fritzthecat,
You have a Noverber 11 1964 car. It is a 65. They changeover was the end of july 64. I have had two 64 1/2 and both were titled as a 65. We in the hobby use the term 64 1/2.
Soaring, speaking of people in the hobby. Many people in this mustang hobby use the term "numbers matching" for date code correct parts on their car. If a cars block,intake,exhaustmanifolds,carb,sheetmetal,steering box ect.. ect.. all fall with in a few weeks before your build date then some people call it numbers matching.  

Thank you very much. When I built the front frame I reused the old radiator brace as I've heard there's something about the vent holes that you can tell about originality of them. Any thoughts?  

A lot of cars, not just early mustangs dont use vin code stamping. There are all sorts of stamps and date codes and manufacturer markings that are part of the fun in researching a car. Foreign cars, seldom used vin code stampings so if it had to be a vin code on a motor then "matching numbers" would be limited to only a few autos that used that. It just aint so !!! Soaring heard this from some GM guy and he keeps repeating it without any knowledge of what it means. Even the Corvette society which is GM and has used vin code stampings for many years will tell you that vin code is only one of the stampings to verify. I quote from Corvette magazine " Another fallacy concerning matching numbers is the fact that if the engine stamping numbers correspond to the VIN, then the car is a matching numbers car. This is not correct. " so they realize that vin code stampings are easy to forge. Anyone with a stamp set can put them on a block. Of all the markings this is one of the easiest to fake,,,and that is on a GM. In 1968 a federal law was passed that mandated vin code stampings on Motor and transmission but before that are a whole lot of vintage cars that according to Soaring we could never call numbers matching. Ferrari did not use vin codes, but the experts know what to look for and what numbers to see.

"In 1968 a federal law was passed that mandated vin code stampings on Motor and transmission but before that are a whole lot of vintage cars that according to Soaring we could never call numbers matching."

And why do you suppose that federal law was passed?  Because people were advertising and selling "numbers matching" cars that were not original factory manufactured whole automobiles, that's why.    You cannot guarantee that if a classic Mustang does not have at least a partial VIN number on the engine and tranny that it is original from the factory.  Sure, you can make a good guess that it is numbers matching if the engine and tranny were built sometime before the car was manufactured, but back then there were literally hundreds of thousands of Mustangs, and anybody could have changed out the engine and/or transmission with another one with a date code prior to the manufacture date.  You cannot guarantee, nor can you legally advertise that a 1965-67 Mustang is numbers matching, because you cannot prove it.  You can guesstimate, but you can't write it in stone.  I just shake my head in disbelief whenever I read an advertisement for a 1965-67 Mustang that is numbers matching.

Does your head jingle when it shakes ???  

No, does yours?  

I dont know Soaring something must be loose in there if you really think they passed a Federal law to protect a guy buying classic cars so he could call it "numbers matching" Ha hahahahaha. I think,,,, now this is just an informed guess Soaring but I think they passed the law because there was a market for used parts when cars were stolen/wrecked and when they were marked at the factory they could be tracked back to a particular vehicle thus hindering thieves. The main point of that law was to make Vin codes more accesible to law enforcement and mandated they be visible thru the windshield.  But your free to fantasize whatever you like. They did the same thing with glass here just a few years ago. But if you think its for the vintage car market,,, then continue with your fantasy.
As far as it being "legal to advertise" I dont think any lawyers or law enforcement are losing sleep over "numbers matching". If you have a 65-67 and it has all the numbers matching then your free to call it that. Knowledgeable people know what that means. If you arent knowledgeable about it, like you, then stay out of the market place. But dont tell people who know better what they can and cannot do.  

Since you guys seem to know about VIN's and such.  Here is one for you.  I am looking to buy a 65 fastback. the VIN on the fenderwell starts with a 4 but the title and door tag start with a 5. The rest of the VIN matches.  Nothing appears to be altered.  what are your thoughts? Ford was no help and i haven't recieved any replys from Marty Reports or any other source i've contacted. to my knowledge Ford never used a 4 with the early mustangs.
