Superformance Chassis Number Identification Guide
This guide will assist you in determining your Superformance car's Chassis identifier number commonly used when determining the pedigree, history and production date of your Superformance.

The Superformance Chassis Number is assigned by Superformance. The "Car Number" is the shorthand Chassis Number identifier for each car. The " *** " below indicate the "car number" we are looking for...

COBRA . . . . . . . . . .

The Superformance Cobra Chassis Number exists in one of these four formats:

1.)   COB** or  COB** - ***   5 or 8 character form: Used on cars up to 031

2.)   AC9CSLK1000AM1***   17 character form: Used on cars 032 through 577 and on cars 579, 580, 582, 583, 584, 586.
                                                             The 5th digit character is "S" for side pipes or "R" for rear exhaust  -  The 6th character is "L" for left hand drive or "R" for right hand drive

3.)   SP***        5 character form:  Used on cars 578, 581, 585, 587, 588, 589, 590.

4.)   SP0****    7 character form:  Used on cars 591 on.

The asterisks (
*) are the Car Number you are looking for that vary from car to car. Even if your VIN number fits this format, it may not be not be your chassis number. The only accurate way to determine the Superformance Chassis Number is as follows.


Locating the Superformance Cobra Chassis Number:

1.)  The Chassis serial number is located on the VIN plate on top of the passenger foot well as viewed from the engine compartment.
       If you suspect the State removed it or replaced it with their own VIN...


A.)
   Open the hood. Look in from the driver's side.

B.)   Locate the upper front cross member. It is just in front of the engine. For reference, it typically has the remote oil filter mounted on it.

C.)  On the top of the cross member about two inches from the left (driver's side) upright, a number is stamped directly on the frame cross member. 
        This is the Superformance Chassis Number. See above for determining your actual "car number."

If you have a metal plate pop riveted in this location, your dealer has covered up the Superformance Chassis Number with you state VIN number.  In this case, do not remove the VIN plate.  Write "Covered by VIN plate" in the space for Superformance Chassis Number.  In this case, it is particularly important that you verify the Car Number as indicated.

The chassis number is also stamped on the hood hinges. Check either hood hinge plate where it is bolted to the hood. The number is stamped into the hinge plate. It may be partially filled with paint and hard to read, but it can be read. The number may also be written in grease pencil in the hinge plate, but use the stamped number.


COUPE . . . . . . . . . .

The Superformance Coupe Chassis Number exists in the below format:

1.)   SPC0 ***   7 character form: Last 3 digits is the car number

The asterisks (
*) are the Car Number you are looking for that vary from car to car.

Locating the Superformance or Shelby Coupe Chassis Number:

The
Superformance version chassis number is stamped on the forward end cap of the upper right hand frame rail just forward of the front upper suspension control arm.
