Fisher Body Unit Number

The Fisher Body Unit Number is unique to Fisher Body meaning it has nothing to do the car's final VIN and will not match the last six digits of the car's VIN.

Unlike the VIN that increases by 1 for each car regardless of the series or body style the body number appears to have no association with the time frame of the build or a particular series or model. This means that any two Chevelles built one after the other would have consecutive VINs such as 101000 and 101001 but the body numbers would not be consecutive or even close to each other.
