The 140 mph speedo was included with COPO 9737, most often seen with COPO 9560 or 9561. All other 1969 Camaros were built with the standard 120 mph or 200 kph speedo. Based on the trim tag this car was built for export and may have had a kph speedo.
I believe you are refering to the scattershield. It was required in sanctioned drag racing to contain debris in the event of a clutch or flywheel failure. It was never factory installed.
This car has been subjected to a number of modifications that suggest it may have been raced. In addition to the scattershield it has sub frame connectors, aftermarket oil pan, headers. It also has an aftermarket radio, missing shifter knob, rocker panel trim, rear bumper guards, spare tire hold-down hook, wrong master cylinder, wrong distributor. There are many incorrect finishes and fasteners. It was built too late for factory 4-wheel disc brakes and chambered exhaust so those were added. It should not have the quarter louver trim and the grille should be argent [silver]. The seller incorrectly states the car has an M21; should be M20. The rear axle code listed is not a 4-wheel disc code.
Draw your own conclusions.
