Is it an actual Impala? Or is it a replica?

Technical data?

It used a wreck of old Impala as a base for custom convertible used in the musical Hair. After a sucessful play the car was parked outside overnight, where some hooligans destroyed it completly and the car was sent to scrap.
I couldnt find any technical data so far, not sure if any dimensons are to be found to be honest.
