I dont know about in 1970,or Van Nuys cars,but I own 3 cars,a 73 Camaro,73 firebird,and a 74 camaro.The number on my frames appears to be a part number,I could never connect it to the VIN trim tag or date{I did change the subframe in the firebird recently}.All my cars had AC,and the hidden VIN on the firewall is near the blower motor.I recently found one more set of numbers on the firebird that do mean something,but I didnt check them on the Camaros.On the bird,I found numbers stamped at the rear of the driveahft tunnel right over the pinion yoke.The numbers are similar to the beggining of the VIN and denote my car as a 1973 Esprit.It would be hard to rebody a 1970-73 Trans Am or Formula using my body shell since these numbers while not the VIN itself do identify the model of the car.
