Hechler ZL-1 info needed

I am in need of some help concerning the 2 ZL-1's that were ordered by Hechler Chevrolet (Richmond,VA) and then DX's to Courtesy Chevrolet. I am really interested in determing what VIN's the cars were and where the cars are now (if known). If the cars are known I might be able to assist the owners, as I am good friends with the then owner/current owner of the dealership. For those not familiar with Hechler, they were the main Corvette dealer/supercar dealer here in Richmond. The yellow ZL-1 'vette and a couple of COPO's were sold there. Any help appreciated.
