maybe old news,but I was cleaning up the area around the passenger side windshield wiper on my 67. The front clip is off so I'm working on the panel under the cowl below the winshield and i notice a #74244917 stamped clearly in this panel. The # seemed familiar,long story short I looked at the VIN and this # is the #'s After the 12337 or 12347 common to all camaro VIN's...anybody else found this # there on their 1st gen

Yep, they are on all of them. There is another one down under the heater fan area too.
