On a 1975 F100, were are all the Vin numbers located?

Yes I found the the door jamb, door post,

 

My 76 has a vin plate under the hood just off center right below the hood line in the back of the fire wall..

 

No such thing as a VIN plate, it's referred to as the Warranty Plate. 1963/79: Located on the left door face below the latch.

Located on the firewall is a "Buck Tag" used by assembly line workers to assure correct parts that match the build sheet are installed.

Codes on buck tags are not the same as stamped on Warranty Plates, cannot be decoded.

DMV/Law Enforcement do not go by VIN's stamped on Warranty Plates, because they're too EZ to change. They go by hidden frame VIN's.

People replaced damaged left doors with used doors. 99.9% of the time, they failed to install the original Warranty Plates on replaced doors.

 

VIN on the frame is on the right front top rail?

Trying to change body parts to fix some rust issues.

thanks,,,,,

 

there's 2 on the frame by the way

 

Where *exactly*? I have never successfully found one of these on any of my Ford trucks.

 

it's a 4wd should be one on top right frame rail by cab mount ???

 

I found a build sheet in my seat bottom between cushion and springs had everthing

 

I have not been able to find my frame #,good luck DMV,Law Inforcement,original Frame,original warranty plate.

 

 

The only people who would go to the trouble to find these stamps are the owners. No way a DMV person or cop is going to go to that much trouble over a 30+ year old truck. Heck even I have been unable in the past but I will try again on my '74 F350 thanks to the excellent photo posted by montana_highboy.

 

As stated above, the "legal" VIN is on top of the frame rail on the passenger side. For law enforcement purposes, all vehicles have a number of "hidden VINS" located on various major assemblies. Even most law enforcement officers don't know where all of these VINS are located. Years ago, there was a boook that came out annually that was made available to law enforcement (NATB book) that gave some of the locations. Even then, it wasn't all inclusive, and if law enforcement needed to know the location of the hidden VINs, they had to contact the National Auto Theft Bureau through the National Crime Information Center NCIC computer. NATB has been replaced by the NICB. I've found some of these hidden VINs on transmissions, rear axle assemblies, engines, and inside body panels. these numbers are usually not the complete VIN, but what are known as partial VINs. usually the sequential serial number and some basic model information.

 

That is incorrect. Kansas checked my '79. anything from another state is checked in Kansas. The patrolman got a wire brush and started looking for it...he knew its location and he found it.

 

x2. CHP (California Highway Patrol) or others will inspect the second "hidden" VIN in frame that many people don't know is there to check for a falsified VIN or stolen vehicle or similar.

Guys trained to look over cars for these reasons know where the "hidden" VINs are from the factory and check for them.

 

It depends .... BT .... DT... with enough PC. Found I had one that was a 15+ year old theft once. Owner was sure surprised and happy until he found out that by accepting insurance $$$ those years ago he gave up any claim so insurance co. got his ..... likely it was sold at auction?

They are called "confidential vins" and they aren't likely to be noticed so easy so they are unlikely to get changed, we had access to a listing that told where they were for whatever vehicle, makes it easier.
