Thanks again Grant.
You are enlightening me already - I am not as familiar with the Chevs as am the Fords.
Tell me about the footwell vents: what the different shapes indicate?
And the compliance plate: how you tell what year?
You also referred to them being in wrong/different location sometimes - what am I looking for there and where do I find any other numbers stamped on vehicle?
I will take more photos when I head back in a week's time.
Thanks so much.
