Finding the ERA Chassis Number

All 289 and 427 cars were stamped on the driver's side front shock mount.  In addition, later cars had the brass plate shown riveted over the actual chassis stamping.

Early 427 cars also had the chassis number molded into the body return lip as shown, althought it may have been lost during body preparation.

The chassis number is also stamped into the side of the right chassis rail above the rear suspension.

Chassis plate
An aluminum ID plate is usually attached to the top of the driver's or passenger's footbox.  The center box in the Serial Number line is the chassis number.  The 427 series is three digits, the FIA and ERA GT, four digits starting with "2".  The Slabside numbers start with a "3".ID Plate
