FERRARI NUMERO INTERNO
The following five sets of numbers are used to determine a "matching numbers" car. These numbers are used to determine the authenticity of a GTE, by matching them with the numbers on the cars build sheet.




Serial Number
This is stamped on an aluminum tag posted in the engine compartment on the right side of the firewall. Information is hand stamped.
Engine Block Number
This is stamped on the Engine Block, left side, near the firewall. The Serial Number is on top and below is the block Number, the year of manufacture and engine type (E).
Chassis Number
Stamped on a brass part of the steering box in the engine compartment. Says "Ferrari 250 GT/E", then the Serial Number (which should match the ID tag). Underneath that is the Chassis Number.
Axle Number
The numbers stamped on the rear of the rear axle housing are: (right) the gear ratio of the axle and (left)the axle number (sequential from the start of the year) over the year of manufacture.
Gearbox Number
Located on a flat horizontal surface on the left side of the gearbox, this is the only number that cannot be seen without disassembling the car. If it is clean, it might be read using a small mirror raised from underneath the car (if the skid plate is off). The top number is the number of the gearbox(sequential from the beginning of the year), over the year of manufacture.


PININFARINA IDENTIFICATION NUMBERS
These numbers are either stamped on metal, written in chalk/crayon on various pieces of the body, to insure that the parts all got to the right car (they should all be the same). Below are the locations I have found so far.




Hood Latch
This number is stamped on the hood latch on the side closest to the firewall. This is the only one I have found that you can see without taking the car apart.
Inside of Door
This number is stamped on the metal frame on the inside of the door, behind the leather cover.
Leather Door Cover
This illegible scrawl was written on the back side of the leather cover on the inside of the door. I have no idea what it means.
Door Kick Plate
A different illegible scrawl, this time on the leather frame on the door that holds the aluminum kick plate.
Leather Radio Cover
This is the part of the dash console that surrounds the radio.
Package Shelf
The illegible scrawl from the leather door cover has returned, this time on the back of the package shelf.
Rear Seat Back
Here is the body number on the back of the rear seat back.
Right Seat Bottom
Here is the body number on the right side of the rear seat bottom.
Left Seat Bottom
I included this photo because it appears to be from the car before it! Anybody out there own Pininfarina Body number 411?
