This is a real Z28, the engine is correct, transmission is correct and rearend. Have confirmed that fact but have been able to put on a lift to to confirm matching #'s. Was told by previous owner that it is a matching #'s car but needs to be certified. You can tell from trim tag this a color change from green to black. The car has been totally restored to a very high standard! Car runs and drive very well and everything work as it should. Video of car running is available upon request.
