I assume you have seen this link. If this is indeed his entire T/A career it would seem he was racing this car just as the heyday of Trans-Am Racing was winding down (Aug. 1971) and the factories pulled out... but that date doesn't square with the pic you have posted above (June 1971). I wonder when he really started...

Regardless, this car would be an awesome build for vintage Trans Am Historic races leading to tons of fun...
