I have a 1973 Challenger, (The Car of the Month - Whoo Hoo), I picked one Flip Top Gas Cap up for a decent price at a Mopar Swap meet, I know it is not stock for my car. I just need to see how it fits from side and top views. Does the early 70's 1/4 differ from the 73 1/4as far as the fuel cap area? Please post pics if you can, Thanks
