I just found an email about this car in my spam box. I'm glad the partial VIN (1KC100126) on the engine pad matches the car's VIN. The "1" before the "KC" stands for Chevrolet. What's the engine assembly code? The engine assembly code is also on the engine pad to the right of the partial VIN. The engine assembly code (if original) can help date the car. As for your question about the cowl tag, "718" is the car's interior trim code = red standard interior with front bucket seats. Is this the interior in the car? I can't make out the number to the right of the trim code in your photo, is it 928-50521?
